13539( 2) - 27-Sep-2013 15:58:09 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 13539 Version: 2 Check-in Time: 27-Sep-2013 15:58:09 STScI Edit Number: 0 Title CCD Imaging Flats Cylce21 ------------------------------------------------------------------------------------ Type Cycle CAL/STIS 21 ------------------------------------------------------------------------------------ Investigators Contact? PI: Dr. Hugues Sana Space Telescope Science Institute - ESA Y ------------------------------------------------------------------------------------ Abstract The program aims at collecting SNR white light imaging flats (aperture=50CCD) for monitoring purposes and to create a new reference p-flat for chronographic (and imaging) observations. ------------------------------------------------------------------------------------ Observations Description ------------------------ Once every 3 months, obtain a series of imaging CCD flats using the MIRROR and the unfiltered 50CCD aperture. The 3 months cadence will allow us to keep monitoring possible (but unlikely) variations across the cycle; while the combined observations will allow us to obtain an average signal ~620000 ADU/pix (similarly to the past cycles) and create a high accuracy (~1%) imaging p-flat. The remaining time in each orbit/visit will be used to monitor the stability of the CORON aperture due to the MSM limited reproducibility. 14.4 seconds of total exposure time with the 50CCD aperture. About 1.2 sec of additional total exposure time will be taken with the 50CORON aperture, as it will be possible to fit in a 1800 sec visit. Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- The number of orbits has been halved with respect to the previous cycles. In addition, the set of exposures with the aperture F28X50LP has been dropped. They will be (partly) replaced with the aperture CORON in order to monitor the MSM reproducibility and test the possibility of producing a choronographic l-flat. Cycle 21 unchanged with respect to Cycle20. ------------------------------------------------------------------------------------ 13539( 2) - 27-Sep-2013 15:58:09 - [ 2] Visit: 01 Visit Requirements: BEFORE 15-DEC-2013:00:00:00 On Hold Comments: Additional Comments: CCD imaging monitor: 50CCD and CORON white light flats.
