Principal Investigator Institution Country Telephone R. I. Jedrzejewski STSCI USA 338-4817 ------------------------------------------------------------------------------------ 7. Abstract The principal objective is to measure the location of the post-COSTAR f/96 aperture with respect to the V2V3 coordinate frame. The orientation of the detector and the reseaux axes with respect to the V2V3 axes will be used to update the PDB if necessary (i.e. if the offset from the expected PDB locations is more than 5 arcseconds, which could mean that full-format acquisitions might miss their target). Execution of this proposal and subsequent PDB update if necessary will enable the COSTAR/FOC alignment activities. Modified SMC Proposal "BASELINE FOC/96 APERTURE LOCATION" - RIJ Kept the same ND filters, since the initial aberrations might be as high as for the spherically aberrated PSF (mainly coma). ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

GENERAL FORM Proposal 4931 PI: R. I. Jedrzejewski Proposal Title: POST-COSTAR FOC/96 COARSE APERTURE LOCATION ------------------------------------------------------------------------------------ 1. Proposers: Proposers Institution Country ESA ------------------------------------------------------------------------------------ R. I. Jedrzejewski STSCI USA X ------------------------------------------------------------------------------------ 3. Description of proposed observations. Use Mode III pointing to acquire the selected NGC 188 astrometric field. A dwell scan sequence is then initiated, yielding a further eight exposures at suitable offsets from the nominal target area, with appropriate overlap of the images. The final exposure returns to the nominal position to confirm the position of the 512 x 512 with respect to the extended format. The sequence begins and ends with an "intflat" exposure for tracking image distortion. ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. The observations are required to determine the orientation of the detector and the reseaux axes with respect to the ST V2V3 axes. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. PREREQUISITES: COSTAR FOC arm deployed via prop 4812. Secondary mirror move #2 completed via WFPC2 Coarse Focus prop 4270. ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. The data will be analyzed on the ground to determine i) the detector coordinates of the position of each standard star in each image ii) the V2V3 offset vectors for each star from the known cross pattern step and dwell iii) the orientation of the detector system with respect to the V2V3 axes ------------------------------------------------------------------------------------ 11.
