Proposal_Information Title: GHRS SPATIAL PSF CHARACTERIZATION--CYCLE 5 Proposal_Category: CAL/HRS Scientific_Category: Cycle: 5 Investigators PI_name: SCHULTZ, AL PI_Institution: STSCI CoI_Name: ROBINSON, RICH CoI_Institution: GSFC CoI_Name: WALSH, JEREMY CoI_Institution: ST-ECF Questions Observing_Description: The object of this program is to measure the PSF from a point source in the SSA at various distances from the SSA. This is a combination PSF/scattered light test in that we measure the PSF at several diffferent radii and at the same time obtain a measure of the contributed scattered light from nearby objects. A single scan in the GHRS detector X direction will be taken at 1400 A. A pair of scans in the X and Y directions will be taken at 2700 A. The accuracy goal of this test is 5% absolute at a radial distance of 1.6 arc sec from the center of the PSF at 1400 A. This program need only be executed once during Cycle 5. Real_Time_Justification: Calibration_Justification: This test will be used for close-out and archival purposes and supports 0% of Cycle 5 GO programs. Additional_Comments: The idea is to center up on the star, back off 0.2 arcsec, and scan in one direction, crossing the peak of the PSF and obtaining information out to a distance of 3.0 arcsec from the peak.. Abstract: The purpose of this test is to measure the PSF of a point source in the SSA to evaluate the scattered light contributed by objects within 3 arcsec of the GHRS SSA.
