resubmission to add targets, replacing original targets that could not be cleared in the safety checks. Nov. 19, 2009: another resubmission to revise ACQ strategy (by recommendation of Nolan Walborn) by going back to the 2x2 search (from 3x3 added in substitute target resubmission), but adding XD and D peakups; all this to avoid a new round of safety checks. the 16 substituted targets were left at 3x3, because they are at beginning of safety check process. (by the way, the safety check rationale for the 16 new targets is spelled out toward end of Observation Description in the Phase II proposal.)

Fe XII 1349 (T~ 2 MK) and Fe XXI 1354 (T~ 10 MK) -- well known to Solar Physics -- have been detected in about a dozen cool stars, mainly with HST/STIS. The UV coronal forbidden lines are important because they can be observed with velocity resolution of better than 15 km/s, whereas even the state-of-the-art X-ray spectrometers on Chandra can manage only 300 km/s in the kilovolt band where lines of highly ionized iron more commonly are found. The kinematic properties of hot coronal plasmas, which are of great interest to theorists and modelers, thus only are accessible in the UV at present. The bad news is that the UV coronal forbidden lines are faint, and were captured only in very deep observations with STIS. The good news is that 3rd-generation Cosmic Origins Spectrograph, slated for installation in HST by SM4, in a mere 25 minute exposure with its G130M mode can duplicate the sensitivity of a landmark 25-orbit STIS E140M observation of AD Leo, easily the deepest such exposure of a late-type star so far. Our goal is to build up understanding of the properties of Fe XII and Fe XXI in additional objects beyond the current limited sample: how the lineshapes depend on activity, whether large scale velocity shifts can be detected, and whether the dynamical content of the lines can be inverted to map the spatial morphology of the stellar corona (as in "Doppler Imaging''). In other words, we want to bring to bear in the coronal venue all the powerful tricks of spectroscopic remote sensing, well in advance of the time that this will be possible exploiting the corona's native X-ray radiation. The 1290-1430 band captured by side A of G130M also contains a wide range of key plasma diagnostics that form at temperatures from below 10,000 K (neutral lines of CNO), to above 200,000 K (semi-permitted O V 1371), including the important bright multiplets of C II at 1335 and Si IV at 1400; yielding a diagnostic gold mine for the subcoronal atmosphere. Because of the broad value of the SNAP spectra, beyond the coronal iron project, we waive the normal proprietary rights.
The objective of the program is to record key coronal forbidden lines Fe XII 1349 and Fe XXI 1354 in a variety of active cool stars. These lines fall on detector segment A of the G130M mode. Because the stars of the sample typically also have very bright chromospheric Lyman-alpha emission in the G130M bandpass, it is necessary to power down the B side of the detector for the acquisitions (in dispersed light: see below) and the science exposures. Targets for the Coronal Iron SNAP Survey were drawn mainly from the extensive ROSAT/IUE "Coronathon" program of Ayres et al. (1995: ApJS 96), the "STIS Coronal Forbidden Line Survey" of Ayres et al. (2003: ApJ 583), and the HST/GHRS study of Hertzsprung gap giants by Ayres et al. (1998: ApJ 496). A list of more than 100 potential targets was whittled down to the 40 approved SNAP opportunities by considering the ROSAT X-ray fluxes, which are an excellent predictor of the forbidden line strengths; FUV fluxes, which in some cases grossly exceeded detector safety limits, causing a candidate to be excluded; and whether the object was in fact a close double with separation greater than a few arcseconds, which would be problematic for the COS 2.5 arcsec aperture. A few targets were drawn from a low X-ray flux group, to serve as a control for spectral blends in the vicinity of the two main coronal iron forbidden lines. Thirteen of the target/visits were rated high ("H") priority; an equal number were rated low ("L"); and the remaining 14 were set at medium ("M"). In order to maximize the available exposure time, a simple 2X2 search pattern in dispersed light (with the same grating setting as used for the main science exposure) will be performed following Guide Star acquisition. All of the targets are Hipparcos stars with accurately known coordinates and proper motions, certainly better than 1 arcsecond. The 2X2 search will center the target in the Primary Science Aperture accurately enough for our purposes. There is no need to perform a subsequent peakup in either direction, since these only would improve the wavelength zero point (not a concern in this program, because sharp chromospheric emission lines in the G130M bandpass provide an internal marker for the stellar radial velocity), but at the expense of several minutes of lost exposure time. The spectroscopy search typically is faster than a direct NUV imaging acquisition, when the exposure time at each dwell point is less than a minute or so (the case here thanks to bright chromospheric emission lines in the G130M bandpass). This amounts to a minimum of about 10 minutes for Guide Star and target acquisition, leaving up to 35 minutes of possible science exposure, including overheads, out of the maximum SNAP total of 45 minutes. Exposure times for the G130M acquisitions were determined using the COS-ETC and STIS FUV spectra of the targets from the "CoolCAT" catalog, where available; and from IUE (and GHRS) material otherwise. For this purpose, the CoolCAT spectra were restricted to the specific wavelength range of the G130M setting (either 1291 or 1309) and the A detector segment, and all fluxes below 1 sigma significance with respect to a local smoothed photometric noise level were zeroed, to avoid biasing the counts calculation. For the non-STIS stars (about half the targets), IUE/SWP-LO fluxes were taken from the Coronathon survey -- for the bright multiplets of O I (1305), C II (1335), and Si IV (1400) -- and entered into the "emission line" specification in the ETC to estimate the exposure time. Comparisons of this approach for the stars with both STIS and IUE fluxes showed that the emission-line only exposure times were only slightly longer than those estimated with the full spectrum. In a few of the non-STIS cases, GHRS G140L spectra were available, and these were used in preference to the IUE fluxes. The ACQ exposure times ranged from a low of a few seconds to a high of about 1.5 minutes. Even in the latter case, the dispersed light ACQ was faster than an NUV imaging acquisition. The exposure times were calculated to achieve S/N=40, although an acquisition probably would succeed at only 20; so the exposure times are conservative. The specific ETC run numbers are provided in the "comments" section of each ACQ-SEARCH module, in lieu of tabulating the stellar fluxes in detail. The science exposure will be taken using G130M, mainly the 1291 setting, but in a few cases 1309 to avoid over-bright atomic oxygen lines between 1302-06. Only segment A of the detector will be utilized, as mentioned earlier, because the H I Lyman-alpha emission of most of the stars exceeds safety limits. An exposure of 25 minutes (1500 s) was estimated to achieve adequate S/N at the coronal iron forbidden lines in even the fainter targets, and this was adopted uniformly for all the objects. In all cases, the total duration of the observation is less than 45 minutes; for the shortest exposure acquisitions, it is only about 38 minutes. Each 1500 second T-TAG exposure was FP-SPLIT between POS3 and POS4, to suppress fixed pattern and avoid detector artifacts. A more aggressive FP-SPLIT was judged to be too time consuming. A buffer time of 640 seconds was chosen for each 750 second exposure segment to minimize overheads. Postscript: After vetting the Phase II program through the safety check procedure, 16 of the original targets were disallowed. Accordingly, 16 new targets (Nos. 41-56) were added to the program, mainly from a pool of FUSE observations of late-type objects having small proper motions: that is one of the most effective means of safety checking a source, because the interloping 16th magnitude O5 stars of potential concern would leave a clear continuum signature in a typical deep FUSE observation. During the process of revising the program, one of the original SNAP targets -- No. 28, Mu Velorum -- fortuitously was observed by COS. While the observation was successful, and a good quality spectrum was obtained, the target image appears to have been partially out of the PSA, reducing throughput. This likely was a consequence of the minimal 2x2 acquisition search. It was decided, therefore, to revise the dispersed light searches to a 3x3 pattern, and use the FLR option on the centering to boost contrast (allowing in some cases for reduction in the target S/N at the peak pointing, from 40 to 30, thereby permitting shorter exposures and less of an impact from the larger number of dwell steps). The science exposure times were reduced accordingly, to adhere to the SNAP maximum of 45 minutes. In most cases, this was less than a 10% reduction from the original exposure times. Two of the new targets are optically faint, but coronally bright G dwarfs from the Alpha Per cluster (drawn from the "Sleuthing the Dynamo" FOS/GHRS program [Ayres, PI] of the 1990's). The predicted acquisition times were long enough that it was judged better to attempt a "blind pointing," given the accurately known coordinates. Five of the new targets are Hyades dwarfs, also drawn from the "Sleuthing" program. These are bright enough to perform the 3x3 search in a reasonable amount of time. A check of SIMBAD and Aladin showed that the fields around the 7 cluster dwarfs (which all are faint enough optically that they don't overexpose the survey plates) are clear of 16th magnitude objects in the present epoch (with the known proper motions of the cluster stars). All the other targets are cleared on the basis of lack of significant FUV continuum emission in FUSE pointings. Postscript II: in mid-November 2009, one of the STScI support scientists recommended that the new 3x3 searches for the 24 original targets that passed safety checks should be replaced by the original 2x2 searches, but adding XD and D peakups. This was said to reduce the possibility that the 24 would have to be safety checked all over again. It was OK to leave the 3x3's in for the 16 replacement targets, since these would have to be safety checked from the beginning. The two approaches should yield comparable centering accuracy, and both require about the same amount of time. The PI slightly prefers the 3x3 because it covers a 4x larger area, and one can use the "FLR" option on the centering to improve contrast of the search peak. It was decided to revise the original 24 "passed" targets for the 2x2's plus peakups, and leave the 16 replacement targets as is, i.e., with the 3x3's. If nothing else, this will provide a good post-facto comparison of the two acquisition strategies. After adjusting each sequence to meet the 45m limit, the typical on-source exposure time was 1300s compared with the original 1500s.

Similar results were obtained taking Alp Boo to be 10X, and Alp Tau 5X, the target in the FUV.

The scaling was according to the ratio of the observed C IV 155 nm fluxes (from FOS, for the Alp Per stars: MEL20-350 and MEL20-709 have similar fluxes). The DISP/ACQ simulations are overestimated, since selective HI absorption and reddening will diminish the Alp Per Ly-alpha profile compared with that of 10X nearer Chi1. Even so, the predicted 175s per step was judged to be too long, so a blind acquistion is preferred.
