PI: Dr. John W. MacKenty Space Telescope Science Institute CoI: Dr. Peter McCullough Space Telescope Science Institute N ------------------------------------------------------------------------------------ Abstract This program tests the performance of spatial scans and the WFC3 IR channel. Observations of a spectrophotometric standard star will determine the velocity vector of motion and its controlability and repeatability. It will also answer some basic questions regarding the initiation of a scan (ramp up and offset positioning). These measurements will also serve to obtain a confirmation of the imaging photometric zero point for the IR channel and the residual errors in the flat field. ------------------------------------------------------------------------------------ Observations Description ------------------------ The standard star P330E is placed at the nominal center of the IR detector (default aperture location).

Please keep blocks of exposures together: i.e. keep exposures 1-6, 7-10, 11-17, and 18-23 together. If the ORIENT constraints impact scheduling, please realize that the ORIENT constraint is not critical and can be relaxed, especially for Visit 1 (with no grism spectrum, just trailed stellar PSFs); the ORIENTs that would be worst are 14 degrees + N*90, with N = 0, 1, 2, 3, because ORIENT=14 degrees corresponds to the PA of the nearest bright star (59 degrees) to the target minus 45 degrees (the detector orient w.r.t. to due North). APT predicts that the ORIENT constraints expressed in this Phase 2 change the window of schedulability of Nov 12-27 into two windows Nov 12-16 and Nov 21-27. If schedulers need to put this program in the Nov 16-21 window in order to schedule it in 2010, then proceed anyway - the chance of overlapping trails is still very very small. Getting some data expediently is more important than non-overlapping trails.

This visit consists of three non-interuptible sequences, and IR one, a UVIS one, and an identical copy of the IR one. Ideally, we would fit the first two sequences into the first orbit and the third one in the second orbit (in which case the rest of the second orbit can be used simply to keep repeating the forward-reverse pairs of exposures 6 and 7 again and again until the visibility ends). An orientation of 80.68 degrees would match that actually observed in visit 2 of program 12251, which would simplify comparison of the spatial scan spectra with that of nominal spectra. It also would help us know what confusing sources might overlap the spectra. However, orient 80.68 degrees is not available until the Fall, so we choose a wider range of orients that can be observed in April or May 2011. In program 12251, they avoided orient 196 deg by 15 degrees to assure the spectrum of the nearest bright star (16 arcsec away at PA=151 deg) wouldn't come within 30 rows of the target spectrum. We expand that to 80 rows in order to accomodate 50 rows of scanning (plus the same 30 rows for PSF wings), which gives orient constraint of 56 to 156 degrees or 236 degrees to 336 degrees. (The roll angle report suggests an orient range of 260 to 290 degrees will allow it to schedule before May 5, 2011.) The phase constraints ensure that the planet is in transit for at least 3/4 of the second orbit of the visit. That will astrophysically match this program's second visit and second orbit to the third orbit of visit 2 of program 12251. We assume the HST orbit is 96.0 minutes long. NOTE: the phase constraints given for the first direct image that initiates the non-interupptible sequence are desired but not required for this engineering test. Please do not delay the test past April 24, 2011 in order to match the phase constraint, but if all other things are equal, please use these phase constraints. If the phase constraints can be adopted, this engineering test will also produce excellent scientific added value to program 12251. However, the engineering test is time critical and expediency should be a very high priority. If the visit cannot be scheduled until after April 24, 2011 in any case, please do not delay more than an additional 4 days to meet the phase constraint. Bottom line: schedule as you please, but if you can also schedule with the phase constraint, please do! The POS TARG on the direct image along with the SAME POS on the staring-mode grism exposures makes the direct image on the same quadrant as the zeroth order image and approximately on the same rows as the first order spectrum and the zeroth order image appear. We quote from proposal 12251: "We position our target such that the direct image is located at pixels (505 px, 532 px). As described by L. Petro (TIR 2010-03), this location optimally avoids known bad pixels and IR blobs while keeping both the 1st order spectrum from crossing an amplifier boundary and the 0th order spectrum in view on the subarray. As calculated in TIR 2010-03, we introduce a POS TARG of (-2.303", 1.202") to offset the target from (522 px, 522 px), the fiducial pixel for the IRSUB512 aperture we are using." NOTE that we are not allowed to use "SAME POS" with spatial scans, so we cut and paste the POS TARG above to each scanned exposure. Implementation Notes: Originally PERIOD 1.5804075D and ZERO-PHASE HJD2454983.908864 were specified on the Visit. This was replaced by a BETWEEN to accomplish the intention with the SPSS scheduling. The scheduling requires a break in the original NON-INT SEQUENCEs after exposures 6 and 24 Two additional WFC3/IR exposures added to the end of the Visit. These will be used to validate better timing offsets between the start of the exposure commanding and the start of constant velocity of the scan. 12325( 10) - 06-Apr-2011 19:53:52 - [ 9] Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| | Requirements ------------------------------------------------------------------------------------------------------------------------------------ Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 GJ1214 WFC3/IR MULTIAC IRSUB512 F130N NSAMP=3, SAMP-SEQ=RAPID 1 DEF POS TARG -2.303, 1.202; CUM SEQ 1-6 NON-INT Comments: Originally this exposure contained PHASE 0.942 TO 0.954 which was replaced by a BETWEEN to implement the intent. ------------------------------------------------------------------------------------------------------------------------------------ 2 GJ1214 WFC3/IR MULTIAC IRSUB512 G141 SAMP-SEQ=RAPID, NSAMP=7 2 DEF SAME POS AS 1 CUM Comments: These two staring mode grism spectra replicate the type used in program 12251, except there the sequence was of 48 of these.

Please keep blocks of exposures together: i.e. keep exposures xxx together. HD 80606 is a double star, which restricts the length and orientation of any scan to avoid overlap of spectra.
