From: shireen@stsci.edu Proposal_Information Title: WFPC2 CYCLE 6: PHOTOMETRIC TRANSFORMATION Proposal_Category: CAL/WF2 Scientific_Category: Cycle: 6 Investigators PI_name: WHITMORE, BRAD PI_Institution: STScI Questions Observing_Description: PURPOSES 1) Update photometric transformations to Johnson-Cousins system and Stromgren system 2) Determine spatial dependence of contamination 3) Check the astrometric solution using M67 4) Spot check of gain = 7 vs. gain = 15 ratios 5) Spot check short vs. long exposure zeropoints 6) Provide chip-to-chip zeropoint check in UV. 7) Map out vignetting in F160BW and F160BN15. DESCRIPTION Three photometric standard star fields in NGC 5139 (= Omega Cen; metal rich), NGC2682 (= M67; metal poor), and NGC2100 (young cluster) are observed before and after a decontamination. Four different filter sets are used. # 1 - The five filters generally used to match the Johnson-Cousins system (F336W, F439W, F555W, F675W, F814W). #2 The wide-band equivalents for the Johnson-Cousins system (F300W, F380W, F450W, F606W, F702W). # 3 - The Stromgren-equivalents (F336W, F410M, F467M, F547M). # 4 - Two filters farther toward the UV (F255W, F170W), so that contamination over the full field of view can be measured. F255W is not used for the reddest cluster (NGC5139). F170W is only used for the bluest cluster (NGC2100). For the brighter clusters (NGC2682 and NGC2100) long and short exposures are taken in the UBVRI equivalents both to extend the dynamic range and to check for differences in photometric zeropoints. A spot check to compare gain=7 and gain=15 is also included for NGC5139 and NGC2682. For NGC2100, three positions are observed on the PC1 for F170W and F160BW, and three positions on WF3 for F160BN15, to map out the spatial dependence, and vignetting, using a bootstrap technique. RESOURCES - 12 orbits SPECIAL REQUIREMENTS - The first visit for each target must be taken within 3 days after a decontamination. The second visit, including only the UV filters, must be taken more than 25 days after the first visit, but before the next decontamination.
