              Title: GHRS Far UV Throughput without COSTAR Mirrors -- Cycle 6 closeout

Abstract:
In order to determine if COSTAR is the sole cause of the loss of
throughput at the short-wavelength end of GHRS, we intend to make
a series of measurements of 2 stars just before and just after
the removal of the GHRS COSTAR mirrors.


Questions


    Observing_Description:
This proposal defines the 2nd of a set of two proposals that will
monitor the sensitivity calibration of the GHRS Side 1 low resolution
grating (G140L) at 2 wavelengths (1200, 1500) and the Side 2 medium
resolution gratings (G160M, G200M, G270M) at 5 wavelengths between 1200
and 3000 A through the LSA with the UV spectrophotometric standard
stars AGK+81D266 and BD+75D325 (and BD+28D4211 -- but only if there is
a significant change in date of SMOV).  The exposure times are
relatively short.  This proposal does essentially the same measurements
as previous sensitivity monitoring proposals except that instead of the
normal standard star (BD+28D4211) used for GHRS sensitivity monitoring,
the other 2 stars observed at the end of Cycle 3 are being measured.
(BD+28D4211, unfortunately, becomes unaccessible a few weeks before the
Feb 97 Servicing mission date.) The measurements are to be made just
AFTER the GHRS COSTAR mirror removal in anticipation of the Feb 97
Servicing Mission where GHRS will be removed completely.  A second
observation of BD+75 is thrown in to increase our chances of obtaining
successful measurements.

      Additional_Comments:
In order to determine if COSTAR is the sole cause of the loss of
throughput at the short-wavelength end of GHRS, we intend to make a
series of measurements of 2 stars just before and just after the
removal of the GHRS COSTAR mirrors.  We would like to be able to tie
these measurements, at least in time, to our normal standard star,
BD+28D4211 which, unfortunately, becomes unaccessible a few weeks
before the Feb 97 Servicing mission date.  We have split these
observations into 2 proposals due to the special considerations that
need to be taken into account for making GHRS observations without
COSTAR mirrors.
