Abstract This test performs the routine monitoring of the GHRS detector dark noise. This proposal will provide the primary means of checking on health of the GHRS detector systems through frequent monitoring of the background count rate. ------------------------------------------------------------------------------------ 8.

GENERAL FORM Proposal 5039c PI: Dr. Stephen J. Hulbert Proposal Title: GHRS DARK NOISE MONITORING -- CYCLE 3 ------------------------------------------------------------------------------------ 1. Proposers: Proposers Institution Country ESA ------------------------------------------------------------------------------------ Dr. Stephen J. Hulbert STSCI USA ------------------------------------------------------------------------------------ 3. Description of proposed observations. Engineering mode "Photoscan" will be used. An integration time of 10 seconds with 7 bins produces a readout every 70 seconds. It is necessary that each bin contain consecutive 10 second integrations. 16 of these observations provides 18.7 minutes of dark count data. All deflections are 2048, 2048. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. Estimated observing time = 24 exposures x 18.67 minutes = 448 minutes = 7.47 hours. Guiding Tolerance: none - internal test only These are internal tests and do not require any special pointing of the telescope. There is no carrousel motion. Lines 11, 21, and 31 should be executed completely WITHIN the SAA--Lines 10, 20, and 30 should be executed outside of the SAA but should not be interrupted by an SAA passage. ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. The basic goals are long term trend analysis and improvement of statistical accuracy. ------------------------------------------------------------------------------------ 11.
