Abstract This proposal performs the absolute calibration of the HSP for filters used in the GO or GTO Cycle 3 program. A relatively bright photometric standard (V > 9) is observed at through all the filters being used on each detector. The observation is repeated every 2 months to monitor the calibration and to allow interpolation to points in between the measurements. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

GENERAL FORM Proposal 5022c PI: Dr. Robert C. Bless Proposal Title: HSP PHOTOMETRIC CALIBRATION-CYCLE 3 ------------------------------------------------------------------------------------ 1. Proposers: Proposers Institution Country ESA ------------------------------------------------------------------------------------ Dr. Robert C. Bless UNIV OF WISCONSIN USA Ms. Lisa E. Walter SPACE TELESCOPE SCIENCE USA INSTITUTE ------------------------------------------------------------------------------------ 3. Description of proposed observations. All the standard stars to be used have similar colors in the visual and UV range; they are all white dwarfs or peculiar O stars with good ground and space- based photometric calibrations. A sequence is defined for each HSP detector with the relative exposure times in each filter specified. When the sequence is used, the exposure times are multiplied by a scale factor which depends on the brightness of the particular standard star being observed. The exposure times (with the multiplier) are chosen to give about 1E6 counts per filter, so that the signal-to-noise ratio of the measurement should be about 1000. Data are always collected using DATA-FORMAT=ALL so that the analog-to-digital conversion can be calibrated for filters with higher count rates. The total exposure time for the observation of a star will usually be determined by the overhead time required to slew from one filter to another; the stars were chosen to be bright enough that the actual time spent collecting data will not be large. Since the slew time between filters is about 30 s, reducing the exposure times below about 10s is a wasteful efficiency. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. The observation is to be repeated a total of 6 different times through the year, with possibly a different target being used each time depending on which targets are far from the Sun and which are conveniently located in the sky near other HST targets (or which are being used for other HST calibration observations.) This cannot be specified very well on the forms, but that is our intention. ------------------------------------------------------------------------------------ 6. Description of special calibration exposures. No special calibrations, dark time, or uninterupted exposures are requested. ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. The data will be reduced by comparing the count rates in the various observations with synthetic photometry based on the HSP filter and detector response curves and the absolute spectrophotometry of our standard stars in CDBS. If HSP is very stable (as is hoped), then these HSP observations can be used to improve the relative calibration of the HST standards. Results from the analysis will be used to populate the relative sensitivity parameters in CDBS for use in pipeline calibration of HSP data. ------------------------------------------------------------------------------------ 8. Additional comments or special requests. No supporting or coordinated observations with other facilites are anticipated. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). Data reduction and analysis will be carried out at STScI with CDBS. ------------------------------------------------------------------------------------ 11. Address Information Page 3 Name: ROBERT C.
