Principal Investigator Institution Country Telephone Charles (tony) Keyes STSCI USA 301-338-4975 ------------------------------------------------------------------------------------ 7. Abstract In cycle 3 we will continue our program of monitoring y-bases by measuring the locations of spectra for the 0.3" aperture at all grating settings once every 2.5 months to verify repeatability and to measure any long-term drift. This test has the highest priority because our ability to acquire spectra depends on our knowledge of Y_Base balues. Total spacecraft time is 1.9 hours of NON-PRIME time. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Description of proposed observations. In this test, we will obtain data on the internal Pt-Ne lamps. Data will be obtained through the 0.3" apertures for 8 dispersers. The observations will map the face of the photocathode using 24 y-steps and 1 x-step. The program is to be performed for a total of 3 times, once every 75 days (plus or minus 10 days) starting 1 JUL 1993. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. All observations should be performed in NON-PRIME time. Each sequence should be performed within a 12 hour timeframe. Note that the high voltage MUST NOT be turned off (except possibly for SAA passages) once a sequence has begun. ------------------------------------------------------------------------------------ 6. Description of special calibration exposures. This test is not stray light sensitive. All observations are internal Pt-Ne lamp measurements. ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. Data reduction and analysis will be performed at the STScI. This is a verification of ground-based analysis, so no data will need to be added to the PODPS pipeline. However, this program will determine the correct y-deflections to be used in obtaining data, and this information will need to be updated after any change in position is measured. ------------------------------------------------------------------------------------ 11.
