abstract:

    line_1:        The aim of these tests is to measure the plate scale of the FOC f/48, f/96 and
    line_2:        f/288 modes and to determine the distortion over the field, using a rich star
    line_3:        field in the globular cluster 47 Tuc, which will be placed in different
    line_4:        positions on the detector.
    line_6:        These tests may have to be repeated after the SV period, depending upon the
    line_7:        long term stability of the instrument.
    line_9:        The observations will be analyzed off-line using CDBS, and the analysis will be
    line_10:       used to update the FOC reference files in SOGS.

  question:        3
    section:       1
    line_1:        This test determines the plate scale and distortion of the FOC. The basic
    line_2:        philosophy is to take three exposures of a rich stellar field and control the
    line_3:        displacement of the individual exposures with the FGS to obtain the plate scale
    line_4:        and its variation over the FOV.
    line_5:        To achieve adequate coverage, the 512 x 1024 format (square pixels, 8-bit) is
    line_6:        used.
    line_7:        All observations are cycle 0.
    line_8:        NOTE TO SCHEDULER: The sequences in lines 1-6, 15-20, and 29-31 on the exposure
    line_9:        log sheet are to be carried out IN ORDER and with minimum gap between individual
    line_10:       exposures. We require good geometric stability from the FOC for these sequences,
    line_11:       hence we have interleaved internal LEDs with the stellar exposures to allow us
    line_12:       to monitor stability during our subsequent analysis. During the LED exposures we
    line_13:       require the HST to remain on-target; and the LEDCAL exposures can be made
    line_14:       through filters (F480LP for f/96, F305LP for f/48) to minimize the time between
    line_15:       individual exposures.
    line_16:       The F/288 mode should be done several weeks after the f/96 exposures, to allow
    line_17:       us time to find a suitable subfield in 47 Tuc that will accommodate the 3.8 x
    line_18:       3.8 arcsec(squared) field of view.
    line_20:       The use of NGC104 over NGC188 is strongly preferred. Using NGC188 will
    line_21:       significantly degrade the quality of the test results.

  question:        5
    section:       1
    line_1:        Prerequisites: FOC optical focus (Test 1507) completed; ability to do
    line_2:        ModeIII target acquisition and make small angle maneuvers (10 arcsec).
    line_3:        Good OTA focus.
    line_5:        NGC188 IS AN ALTERNATE TARGET IF NGC104 IS NOT VISIBLE.
