ABSTRACT
This proposal will take a lamp spectrum at a single CENWAVE setting of each of the CCD spectroscopic optical elements, G230LB, G230MB,
G430L, G430M, G750L, and G750M. The exposures here are repeats of selected exposures that were taken in June 2001 as part of the Cycle 11
CAL/STIS program 9617. The location of each spectrum on the detector will be compared with the pre-repair observations, to look for operationally
signficant shifts. The observed line-widths will also be compared with the previous observations to look for any changes in spectral resolution.
Proposal 11385 (STScI Edit Number: 0, Created: Friday, January 18, 2008 8:34:28 AM EST) - Overview
OBSERVING DESCRIPTION
For each STIS CCD grating, a HITM lamp spectrum will be taken to verifiy how the spectra project onto the STIS CCD detector. These exposures
are repeats of selected exposures from CAL/STIS cycle 11 program 9617. This proposal fits into a single 1800 s internal visit.
This proposal should execute any time after STIS-08 (11383) "aperture wheels and lamp test" has completed, but there is no need to evalulate the
data from that proposal before this one executes.
For each lamp spectrum obtained, compare the position of the spectral lines and the locations masked by the aperture bars to corresponding
observations from program 9617. Look for any unexpected or operationally significant shifts in how the spectrum is projected onto the detector.
Also, compare the line profiles for selected spectral lines to check for any changes in spectral resolution or focus across the detector. Look especially
for any changes that are significant enough to affect operations or science data quality, or which might require table or database updates.

Diagnostic Status: No Diagnostics
Scientific Instruments: STIS/CCD
Special Requirements: GYRO MODE 3GOBAD
Comments: Repeats of selected exposures from CAL/STIS cycle 11 program 9617.
That program used the HITM1 lamp instead of the LINE lamp that
had earlier been used for these dispersion checks, as HITM1 better
illuminates the top of the CCD near the E1 position.
