Abstract There is a SMOV DQE proposal that measures the F/96 DQE using 8 filters. This Cycle 4 proposal fills in the gaps in wavelength coverage left by the SMOV proposal while also checking those filters requested by GOs and GTOs. The filters checked are: F120M, F130LP, F140W, F152M, F165W, F175W, F190M, F220W, F253M, F275W, F278M, F320W, F342W, F346M, F372M, F430W, F480LP, F410M, F501N, F502M, and F550M. This proposal, in using these filters, not only helps determine the DQE for the FOC+COSTAR, but it also determines the transmission characteristics of some wide-band filters and prisms, and updates our understanding of the format dependence nature of the FOC responsivity. Furthermore, images are taken to check that the ND filters respond as predicted; a crucial factor with the COSTAR-corrected PSFs. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Description of proposed observations. To measure the throughput of the OTA + FOC we shall image a UV-optical spectrophotometric standard through a sampling of F/96 filters which will be used by GOs and GTOs during Cycle 4. The filters have been precisely calibrated at the unit level. As we know their transmisison characteristics accurately, and we know the flux of the standard star, we can determine the sensitivity of the OTA + FOC from the observed FOC photon counts. The throughput must be evaluated at a number of different wavelengths. The results will be compared to those obtained prior to the installation of COSTAR. In addition to determining the DQE of the FOC+COSTAR, some requested wide-band filters will be used with the prisms to obtain the transmission characteristics of the filters, specifically looking for redleak. This requires the use of a second target, BD+75D325, to check the redleak for F320W as requested by a GO, while the F175W(GO requested this), F275W, F140W, and F130LP filters use HZ4. With the increased importance of the ND filters, the F2ND, F4ND, and F6ND will be checked with a F210M filter, while the F1ND filter is checked with the F501N and F210M filters. Furthermore, the F210M filter is used to check the format dependence of the 512zX1024, 512X512, 256X1024, 256X256 and 128X128 formats. ------------------------------------------------------------------------------------ 5.
