13148( 2) - 01-Oct-2012 10:34:18 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 13148 Version: 2 Check-in Time: 01-Oct-2012 10:34:18 STScI Edit Number: 0 Title MAMA FUV Flats ------------------------------------------------------------------------------------ Type Cycle CAL/STIS 20 ------------------------------------------------------------------------------------ Investigators Contact? PI: Dr. Elena Mason Space Telescope Science Institute - ESA Y ------------------------------------------------------------------------------------ Abstract This program aims at obtaining FUV-MAMA flat-field observations to create a new p-flats with a SNR of ~100 per (low resolution) pixel. The flats are obtained with the Krypton-lamp and the MR grating G140M, similarly to the cycle 17 and 18 programs. However the exact instrument setup (slit width and central wavelength) might change depending on the desired count level (which will be close to the internally allowed global rate limit). ------------------------------------------------------------------------------------ Observations Description ------------------------ Past experience and observations have shown that ~11 visits are sufficient to create a cumulative image with ~2500 counts/pixel (high resolution mode, equivalent to ~10000 count/pixel in low resolution mode). We will start taking exposure with the setup G140M/52x0.1/1470 (as in the cycle 18 program) and move to G140M/52x0.1/1420 as soon as the global rate has decreased below 180000-190000 counts/sec (maximum allowed is ~280000 count/pixels). On the basis of past experience exposures will be at least 4740 sec long. Hence, all orbits exceed the 1800 s execution time. Different visits will have different slit offsets in order to illuminate the pixels which are normally shadowed by the slit bars. Observations in Cycle 19 were not done. Similarly to the NUV flat program, the observations are executed on alternate cycles, to save lamp lifetime. In addition the achievable SNR is limited other than the Poisson noise so that there is no need to collect an infinite number of exposure. Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- At the time of the submisson there are no changes with respect to the cycle 18 program. However the instrument setup might change to G140M/52x0.1/1420 as soon as the 13148( 2) - 01-Oct-2012 10:34:18 - [ 2] global count rate will have decreased below 180000-190000 counts/px. For this reason each visit should be scheduled ~30 days after the previous, thus to allow the frame inspection and the submission of a new APT version, if necessary. ------------------------------------------------------------------------------------ 13148( 2) - 01-Oct-2012 10:34:18 - [ 3] Visit: 01 Visit Requirements: BEFORE 15-NOV-2012:00:00:00 On Hold Comments: Additional Comments: FIrst visit ASAP to check lamp intensity.
