15390( 3) - 02-Nov-2017 17:35:06 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 15390 Version: 3 Check-in Time: 02-Nov-2017 17:35:06 STScI Edit Number: 1 Title STIS CCD Spectroscopic Dispersion Solution Monitor ------------------------------------------------------------------------------------ Type Cycle CAL/STIS 25 ------------------------------------------------------------------------------------ Investigators Contact? PI: Dr. Daniel E. Welty Space Telescope Science Institute Y ------------------------------------------------------------------------------------ Abstract Monitor wavelength calibration / dispersion solutions for STIS CCD modes. Internal wavecals will be obtained for representative wavelength settings with all 6 gratings (G230LB, G230MB, G430L, G430M, G750L, G750M) supported for use with the CCD. All observations will be obtained with the 52x0.1 aperture, which maps to 2 pixels at the CCD. The HITM1 lamp will be used, rather than the LINE lamp. ------------------------------------------------------------------------------------ Observations Description ------------------------ Observation summary: Internal wavecals (TARGET=NONE, LAMP=HITM1, GAIN=1 or 4) will be obtained for representative wavelength settings with all 6 gratings (G230LB, G230MB, G430L, G430M, G750L, G750M) supported for use with the CCD. All observations will be obtained with the 52x0.1 aperture (which maps to 2 pixels at the CCD) and at a lamp current of 10 mA. This program is identical to Cycle 24 program 14825, except for several changes related to the fading of the lamp: (1) the G230MB/1713 setting has been dropped (too few measurable lines), (2) multiple (and slightly longer) exposures will be obtained for G230MB/1995 and G230MB/2416, and (3) the exposure times for several other settings have been slightly increased. Timing request: all three visits to be obtained within a 48 hr span, between 2018Jan01 and 2018Apr30 ------------------------------------------------------------------------------------ 15390( 3) - 02-Nov-2017 17:35:06 - [ 2] Visit: 01 Visit Requirements: BETWEEN 01-JAN-2018:00:00:00 AND 30-APR-2018:00:00:00; GROUP 01, 02, 03 WITHIN 48H On Hold Comments: Additional Comments: Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 NONE STIS/CCD ACCUM 52X0.1 G230LB 2375 LAMP=HITM1, GAIN=4 1 240.
