11431( 4) - 18-Apr-2008 19:14:15 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 11431 Version: 4 Check-in Time: 18-Apr-2008 19:14:15 STScI Edit Number: 2 Title UVIS Hot Pixel Anneal ------------------------------------------------------------------------------------ Type Cycle Parallel Pointing Tolerance SM4/WFC3 17 ------------------------------------------------------------------------------------ Investigators Contact? PI: Dr. Sylvia M. Baggett Space Telescope Science Institute ------------------------------------------------------------------------------------ Abstract The intent of this proposal is to demonstrate the ability to perform UVIS anneals; the first anneal should be executed within 30 days of the initial cooldown of the WFC3 UVIS detector, followed by a second one 30 days after that. During an anneal procedure, the thermo-electric coolers are turned off and the heaters are turned on, bringing the CCDs up to ~20C and repairing a majority of the hot pixels. Internal exposures are taken before and after each anneal, to allow an assessment of the procedure's effectiveness. This proposal corresponds to activity WFC3-18. ------------------------------------------------------------------------------------ Observations Description ------------------------ Full-frame, unbinned bias and dark frames (5 of each) are obtained immediately prior to and following each anneal; the data provide a means of monitoring changes due to the detector warmup. Two anneals are done, the first within 30 days of cooldown followed by a second one 30 days after that; subsequent anneal procedures will be performed via the Cycle 17 anneal program. Real Time Justification ----------------------- Calibration Justification ------------------------- The acquired bias and dark frames will be compared to baseline images, hot pixel changes will be monitored, and the effectiveness of each anneal procedure will be evaluated. Data will also be combined with that from other proposals to generate superbias and superdark reference files for the calibration pipeline. Additional Comments ------------------- This is SMOV WFC3-18; it can not be run until after successful completion of WF06 (proposal 11419), the CCD functional test, and WF16 (proposal 11429), UVIS TEC performance. The links allow for a little flexibility but we would strongly prefer to have the visits within each set of these SMOV anneals scheduled back-to-back. ------------------------------------------------------------------------------------ 11431( 4) - 18-Apr-2008 19:14:15 - [ 2] Visit: 01 Visit Priority: Visit Requirements: On Hold Comments: Additional Comments: Please schedule no later than 30 days after initial cooldown of the WFC3 detectors.
