Principal Investigator Institution Country Telephone Dr. Ronald L. Gilliland STSCI USA 410 338 4454 ------------------------------------------------------------------------------------ 7. Abstract Flight software 4.0 release will include an important new capability for the GHRS -- return to brightest point following a spiral search. This will become the default target acquisition mode for most observations. This test to be placed in the time line 2-3 weeks after the initial RETURN TO BRIGHT test will allow for maintainence of schedule should an easily correctable problem occur in the first test. This proposal is a slight modification of the sensitivity monitoring proposal (4124) that would normally execute one month later. In this version we include duplicated LSA and SSA exposures to define the SSA photometric sensitivity. ------------------------------------------------------------------------------------ 8.

GENERAL FORM Proposal 4227c PI: Dr. Ronald L. Gilliland Proposal Title: GHRS RETURN TO BRIGHTEST (LSA) TEST PART 2 ------------------------------------------------------------------------------------ 1.

Scientific Justification. A more robust method of performing Mode II target acquisitions with the GHRS is being implemented and will be available for general use early in Cycle 2. This proposal simply tests the effectiveness of the new software by exercising it under controlled circumstances. This is a slightly modified sensitivity monitoring proposal to provide SSA/LSA throughputs. ------------------------------------------------------------------------------------ 3. Description of proposed observations. Part 1: lines 11-13 execute a routine mode II target acquisition on the previously observed target, BD+28D4211 using RETURN TO BRIGHTEST. Part 2: lines 175-195 are taken directly from the sensitivity monitoring proposal no. 4124. Part 3: lines 275-295 are identical to those in part 2 with the SSA replacing LSA. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. All target coordinates and acquistion related parameters are taken directly from the CYCLE1 CAL proposal 3385 for BD+28D4211 that has executed successfully several times. ------------------------------------------------------------------------------------ 11.
