Abstract This proposal defines the procedure for verifying that instrumental magnitudes and colors, derived from observations of selected stellar photometric standards using the VIS photometric IDT, can be transformed to existing standard photometric systems. The test determines the combined ST-HSP (detector-filter-aperture) spectral response for a number of selected filter-aperture combinations for VIS IDT. In addition, the HSP prism operating mode is verified and a comparison of data taken in this mode is made with observations in the single aperture mode to derive the prism transmission losses and color terms. Also, an exposure is taken using the HSP beamsplitter. This proposal has been extracted from SV/HSP 2769 to repeat 4 targets taken in June 1991. These observations failed in June due to Gyro high rate excursions which introduced large vehicle jitter. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Slovak UNIVERSITY OF WISCONSIN USA J. F. Dolan GODDARD SPACE FLIGHT CENTER USA ------------------------------------------------------------------------------------ 3. Description of proposed observations. The proposed observations will begin with the VIS IDT configured in the digital, single aperture mode. After acquiring the first photometric standard star in the 10 arcsec finding aperture, the star will be positioned in the first aperture to be tested. The apertures to be used (and the order to use them) are: b) VIS: F620W,F551W,F450W,F184W,F240W,F355M,F419N,F262M,F400LP,PRISM In addition, a single PMT/VIS exposure in split mode is to be taken. At each aperture position, a total of 100 one (1) second integrations are to be obtained, except for the last aperture. Upon moving to the last aperture, the IDT is reconfigured to the prism mode and a total of 200 one (1) second integrations are obtained. For all onboard acq. use 20x20 steps, 0.5 arcsec steps, varying integrations, brightest object. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. POINTING STABILITY: Coarse track is understood to have less than 19 marcsec stability. That is satisfactory for all observations in the 10" and 1.0" UV1, UV2, and VIS IDT apertures, the PMT, and the 6.0". (finding) POL IDT aperture. HSP requires fine lock for all observations in the 0.65" POL IDT apertures and in all the 0.4" apertures. ------------------------------------------------------------------------------------ 6. Description of special calibration exposures. No special calibrations, dark time, or uninterrupted exposures are requested (see item 5 though). ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. The data reduction will consist of deriving the corrected mean count rates from each of the selected apertures for each of the IDTs and calculating the instrumental magnitudes and colors (e.g. (b-v), (v-r) ). The transformation coefficients will be derived which permit the instrumental magnitudes and colors to be placed on the appropriate standard photometric system in the data analysis process. These coefficients will be supplied to the Calibration Data Base (CDB). ------------------------------------------------------------------------------------ 8. Additional comments or special requests. No need for supporting or coordinated observations with other facilities are anticipated. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). Data reduction and analysis will be supported on two computer facilities at the University of Wisconsin in Madison: a) a VAX 11/780 computer under the VMS operating system with extensive application software, including IRAF/STSDAS; b) a microVAX cluster running under ULTRIX; Both computer facilities support the FITS tape standards and thus can readily access the ST-FITS data export products. ------------------------------------------------------------------------------------ 11.
