GENERAL FORM Proposal 4732 PI: Dr. George Hartig Proposal Title: COSTAR/GHRS FINE ALIGNMENT - X-TILT/Y-TILT ------------------------------------------------------------------------------------ 1. Proposers: Proposers Institution Country ESA ------------------------------------------------------------------------------------ John R Troeltzsch BALL AEROSPACE USA George Hartig SPACE TELESCOPE SCIENCE USA INSTITUTE Ron Gilliland SPACE TELESCOPE SCIENCE USA INSTITUTE ------------------------------------------------------------------------------------ 2. Scientific Justification. This activity will satisfy the following COSTAR SMOV Requirements: 1. Perform GHRS fine tilt scan. Take LSA and SSA spectra at 9 locations in a 3 x 3 grid. ------------------------------------------------------------------------------------ 3. Description of proposed observations. A 5x5 N2 on-board acquisition will be performed to center the target in the LSA. Return to brightest point will be used. Take a standard sequence of image and spectra at setup position and after final return to zero setting to check stability. The GHRS M1 mirror will then be moved to each of the 9 scan points with spectra being taken at each point. Each data sequence will consist of the following: 1. Peakup in LSA and LSA IMAGE 2. LSA spectra 3. Slew to SSA and SSA Peakup 4. SSA spectra The scan grid is shown below. Each grid point is labeled with an x and y coordinate (x,y) followed by the number order (#) of the tilt scan X(x,y)-#. The distance between points is 42 arcsec. X(1,3)-05 X(2,3)-04 X(3,3)-03 X(1,2)-02 X(2,2)-01 X(3,2)-06 X(1,1)-09 X(2,1)-08 X(3,1)-07 ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. Prerequisites: 1. COSTAR/GHRS Coarse Alignment - Focus (prop 4731) Real-time Requirements: realtime uplink required to set COSTAR GHRS mech positions to best position at start of observations. ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. Engineering data will be reduced using the ESS and the COSTAR data analysis system to generate standard sorts and plots. Sorts and plots will be used to: 1. Verify GHRS tilt movements and performance 2. Verify COSTAR electrical performance Science data will be analyzed using the COSTAR/GHRS data analysis system. The following analysis will be performed: 1. Calculate the centroid and encircled energy the image. 2. Calculate the ratio of the SSA to LSA flux for each scan point. Plot the results vs. X-tilt and Y-tilt. 3. Use the results of steps 1 and 2 and the COSTAR opto-mechanical model to determine new positions for the focus, X, and Y Tilt mechanisms. Certain Data Base Updates: 1. None. Possible Data Base Updates: 1. Update default SHP mirror positions in PDB table file. ------------------------------------------------------------------------------------ 11.
