12078( 3) - 01-Apr-2010 21:13:33 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 12078 Version: 3 Check-in Time: 01-Apr-2010 21:13:33 STScI Edit Number: 1 Title Verification of Adjustment to Two STIS MSM Positions ------------------------------------------------------------------------------------ Type Cycle CAL/STIS 17 ------------------------------------------------------------------------------------ Investigators Contact? PI: Dr. Charles R. Proffitt Computer Sciences Corporation ------------------------------------------------------------------------------------ Abstract Two STIS CCD CENWAVE positions (G430M 5216 & G750M 6094) project onto the detector at a row that differs significantly from the nominal position near the center of the detector. This proposal will test the MSM updates to properly center these positions. ------------------------------------------------------------------------------------ Observations Description ------------------------ Two STIS CCD MSM positions project the spectrum onto the detector at positions that differ by about 20 pixels from the nominal location assumed by the SIAF file. This can create problems for observations using small sub-arrays as the spectrum may not fall entirely within the subarray. PR 64774 requests a fix for this problem. This proposal will test that fix and should only be executed after that fix has been implemented. Care should be taken to insure that this proposal is processed in such a way that it picks up that fix. Internal HITM1 lamp spectra through the 52X0.1 aperture will be taken for the updated settings (G430M 5216 and G750M 6094), as well as for the adjacent cenwave settings for each grating. Comparing the location of the aperture bars between the different settings will show the centering of the MSM in the cross dispersion spectrum. For the one of the updated settings a HITM1 lamp spectraum will also be taken through the 0.2x0.2 aperture, and a tungsten lamp image will be taken through the 52X0.1 to check the registration of these grating positions with the unfiltered STIS imaging mode. Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- PR 64774 request changes that this proposal will test. This proposal should only be executed after PR 64774 has been implemented. Care should be taken to insure that this proposal is processed in such a way that it properly includes 12078( 3) - 01-Apr-2010 21:13:33 - [ 2] those changes. ------------------------------------------------------------------------------------ 12078( 3) - 01-Apr-2010 21:13:33 - [ 3] Visit: 01 Visit Requirements: 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| | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 NONE STIS/CCD ACCUM 52X0.1 MIRROR LAMP=TUNGSTEN, GAIN=4 1 1 S ------------------------------------------------------------------------------------------------------------------------------------ 2 NONE STIS/CCD ACCUM 52X0.1 G430M 5093 LAMP=HITM1, GAIN=4 1 10 S ------------------------------------------------------------------------------------------------------------------------------------ 3 NONE STIS/CCD ACCUM 52X0.1 G430M 5216 LAMP=HITM1, GAIN=4 1 10 S ------------------------------------------------------------------------------------------------------------------------------------ 4 NONE STIS/CCD ACCUM 52X0.1 G430M 5471 LAMP=HITM1, GAIN=4 1 10 S ------------------------------------------------------------------------------------------------------------------------------------ 5 NONE STIS/CCD ACCUM 52X0.1 G750M 5734 LAMP=HITM1, GAIN=4 1 5.2 S ------------------------------------------------------------------------------------------------------------------------------------ 6 NONE STIS/CCD ACCUM 52X0.1 G750M 6094 LAMP=HITM1, GAIN=4 1 4.2 S ------------------------------------------------------------------------------------------------------------------------------------ 7 NONE STIS/CCD ACCUM 0.2X0.2 G750M 6094 LAMP=HITM1, GAIN=4 1 4.2 S ------------------------------------------------------------------------------------------------------------------------------------ 8 NONE STIS/CCD ACCUM 52X0.1 G750M 6252 LAMP=HITM1, GAIN=4 1 4.1 S ------------------------------------------------------------------------------------------------------------------------------------ Sub Exposures ------------------------------------------------------------------------------------------------------------------------------------ Target | Exp |Instr | Oper. | Aper |Spectral|Cent.|Primary |Secondary |Iteration |CR-SPLIT |Orbit |Duration Name | Num |Config | Mode | or FOV |Element |Wave.|Pattern Pos |Pattern Pos |Num |Num |Number | ------------------------------------------------------------------------------------------------------------------------------------ NONE 1 STIS/CCD ACCUM 52X0.1 MIRROR none none none none 1 N/A NONE 2 STIS/CCD ACCUM 52X0.1 G430M 5093 none none none none 1 N/A NONE 3 STIS/CCD ACCUM 52X0.1 G430M 5216 none none none none 1 N/A NONE 4 STIS/CCD ACCUM 52X0.1 G430M 5471 none none none none 1 N/A NONE 5 STIS/CCD ACCUM 52X0.1 G750M 5734 none none none none 1 N/A NONE 6 STIS/CCD ACCUM 52X0.1 G750M 6094 none none none none 1 N/A NONE 7 STIS/CCD ACCUM 0.2X0.2 G750M 6094 none none none none 1 N/A NONE 8 STIS/CCD ACCUM 52X0.1 G750M 6252 none none none none 1 N/A 12078( 3) - 01-Apr-2010 21:13:33 - [ 4] Summary Form for Proposal 12078 Item Used in this proposal ------------------------------------------------------------------------------------------------------------------------------------ Apertures 0.2X0.2, 52X0.1 ------------------------------------------------------------------------------------------------------------------------------------ Configurations STIS/CCD ------------------------------------------------------------------------------------------------------------------------------------ Opmodes ACCUM ------------------------------------------------------------------------------------------------------------------------------------ Optional Parameters GAIN=4, LAMP=HITM1, LAMP=TUNGSTEN ------------------------------------------------------------------------------------------------------------------------------------ Spectral Elements G430M, G750M, MIRROR ------------------------------------------------------------------------------------------------------------------------------------ Target Names NONE ------------------------------------------------------------------------------------------------------------------------------------
