abstract:

    line_1:        The aim of this proposal is to test a revised version of
    line_2:        the procedure for observing bright objects with the FOC.
    line_3:        This will be accomplished by makeing a DARK exposure im-
    line_4:        mediately preceding an observation of a faint spectro-
    line_5:        photometric standard star (LB227). The fixed target pointing
    line_6:        will be 30 arcsec north (J2000) of the actual stellar
    line_7:        position-- a pointed uplink will be required to a., make
    line_8:        certain the proper filters are in place and only then
    line_9:        b., move the telescope onto the target for the observation.

  question:        3
    section:       1
    line_1:        This program performs a short test of the revised procedure
    line_2:        to observe objects that are sufficiently bright to damage the
    line_3:        FOC if the filter wheel fails. The original procedure was
    line_4:        laid out in a pair of memos by Baggett and Nota in January
    line_5:        1992. The revised procedure involves replacing the test
    line_6:        exposure of an external target with a test exposure of an
    line_7:        internal target. The target position of the external target
    line_8:        must be at least 30 arcsec from the FOC field of view, so
    line_9:        that if the filter wheel fails and no real time contact with
    line_11:       HST is possible, no damage to the FOC will result.
    line_13:       Each uplink creates a downlink-- you can't send commands
    line_14:       blind. Thus the observing procedure is to watch the tele-
    line_15:       metery to make sure the proper filters are in place. Only
    line_16:       if this is so, should the precalculated SIP be performed in
    line_17:       the uplink window. Note that this requires the uplink to be
    line_18:       pointed. REQ UPLINK does not create a pointed uplink for
    line_20:       fixed targets, just for moving targets. SPSS will have to
    line_21:       manually update the alignment.
    line_23:       For programs with multiple pointings and/or filter sets,

  question:        3
    section:       2
    line_1:        multiple uses of this procedure will be necessary. The bottom
    line_2:        line is that if contact with HST is lost, no possible damage
    line_3:        to the FOC should result from these observations. (Note that
    line_4:        LB227 is too faint to damage the FOC even if the procedure
    line_5:        doesn't work and the filter wheel fails.)
