0 Assigned ID: 1146 ----- Attempting Submission 1 (Wed Feb 27 17:42:31 GMT 2013) ----- For the best data quality, it is strongly recommended that all four FP-POS positions be used when observing at a given COS CENWAVE setting. For the best data quality, it is strongly recommended that all four FP-POS positions be used when observing at a given COS CENWAVE setting. As losses from the detector gap are fairly impactful for any of the longer G130M modes, we are now using G130M/1222 for the medium-resolution exposures. This is a very faint target, so look at the ETC simulations will make clear why we're not particularly worried about fixed-pattern noise. Maximizing the number of FP-POS used is not relevant for this observation, but we do use two FP-POS for every cenwave (including data already obtained) as we can do this without any time losses. 1475203062 ----- Attempting Submission 1 (Tue Jun 18 15:46:35 GMT 2013) ----- ----- Attempting Submission 2 (Tue Mar 25 22:17:12 GMT 2014) ----- The visit planner _has_ been run, for the latest version of the exposures. The green check is there and the "update display" option is grayed out. I even ran a force update, and that still leaves this error, so I'm assuming this is a bug in this version of APT. The warning about FP-POS should be a suggestion, not a warning. It's only helpful for people who have no idea how COS works. See submission comments for more details. The First Study of the Quasar Broad Line Region in the <550A Extreme UV Quasar emission in the extreme UV (EUV, blueward of the hydrogen Lyman limit) is poorly understood, and this is especially true for the shortest observable UV wavelengths (300-550A rest). In particular, although some emission lines have been seen at very low resolution, none have been rigorously identified or studied well. We here propose the first study to definitively identify and characterize emission lines in this wavelength regime. We will observe the brightest quasar showing clear emission lines in the EUV, and compare to extant spectra for other quasars lacking such strong emission, in order to: (1) explore quasar diversity, investigating why the quasar emission spectrum varies so much between objects in the EUV when it does not in the FUV through optical; (2) test photoionization models of the broad emission line region, particularly the existing tension between line production for helium and metal lines; (3) identify emission lines in this poorly understood wavelength regime, to enable inference of the underlying EUV spectral slope, important for quasar physics and ionization of the intergalactic medium. We will conduct a detailed study for extreme UV emission lines in our target, previously observed in the FUV only with extremely low resolution ACS/SBC prism spectra. Most of the data will be taken in G130M, with a mix of central wavelengths to maximize wavelength coverage of the most interesting features. Some G140L data will be taken for continuum calibration and to search for emission lines lying redward of the G130M coverage. Accurate SDSS coordinates allow us to use ACQ/IMAGE only to acquire the target (to S/N=40 for the given time). The target does not come close to violating overlight safety, and GALEX imaging directly verifies no nearby UV-bright objects.
