PRE-COSTAR FOS APERTURE THROUGHPUT VARIATIONS DUE TO OTA FOCUS CHANGES D. J. Lindler and R. C. Bohlin FOS Instrument Science Report CAL/FOS-102 93 August ABSTRACT Since the throughput of the FOS entrance apertures depends on the HST focus, estimates of absolute fluxes from observed count rates require a correction for focus effects. ... The 4.3 arcsec aperture throughput observed by a 1.43 arcsec high diode array varies by approximately 10% over this range. ...

... For high spectral resolution observations the devices permanently located at the N2 focus of the BTA are used (Klochkova, 1995, Panchuk, 1995). However for a number of tasks to be performed, it is needed to rule out the influence of the second and third mirrors, i.e. to realize the high spectral resolution ( ) directly at the prime focus. ... Examine the principal parameters of the PF echelle spectrometer, which is equivalent in spectral resolution to the CCD-equipped MSS (Panchuk, 1995). ...
