Principal Investigator Institution Country Telephone Mark Clampin STSCI USA (410) 338-4711 ------------------------------------------------------------------------------------ 7. Abstract Images of a fairly dense photometric field are obtained at 20 positions in two interleaved scans (overall coverage of .075"x.1") to obtain the pixel to pixel PSF dependence. This test is repeated for the whole photometric filter set (F336W, F439W, F555W, F675W and F814W) to establish the color dependence. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Proposers: Proposers Institution Country ESA ------------------------------------------------------------------------------------ Mark Clampin STSCI USA Sylvia Baggett STSCI USA ------------------------------------------------------------------------------------ 2. Scientific Justification. These calibration tests are performed to characterize the point spread function. ------------------------------------------------------------------------------------ 3. Description of proposed observations. F336W, F439W, F555W, F675W and F814W images will be obtained with step and dwell scans. The fine scans are broken into two .05"x.1" which are interleaved for an overall coverage of .075"x.1". The spacing between images will be .025" in both directions. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. Proposal should be scheduled in the latter part of Cycle 4. ------------------------------------------------------------------------------------ 11.
