abstract:

    line_1:        This test performs a pulse height analysis to determine
    line_2:        individual diode response as a function of threshold for HRS
    line_3:        detector 1. Based on this evaluation new thresholds may be
    line_4:        determined for optimal HRS operation.  Command block
    line_5:        ZCTFLIT1 (PLCP threshold file PZTHR1)  will be updated
    line_6:        accordingly.  This test will run once during the cycle. Also
    line_7:        included is one ion test which is a PHA of twice normal
    line_8:        threshold to look for ion events (which accelerate back up
    line_9:        the 22 kV potential of the tube, liberate electrons from the
    line_10:       phocathode, and produce events of twice normal energy (this
    line_11:       should be a very low, stable rate)).

  question:        2
    section:       1
    line_1:        GHRS Objectives:
    line_2:        1. Verify threshold electronics.
    line_3:        2. Determine the optimal HRS thresholds.
    line_4:        3. Check on ion events.

!

  question:        3
    section:       1
    line_1:        The HRS DEBs are turned on, and the ZCOPHA command block is executed
    line_2:        to generate the required science data. The default thresholds are then
    line_3:        reloaded and verified.  An ion count will be performed
    line_4:        in addition to the PHA. The same command block (ZCOPHA) is used for
    line_5:        both the PHA and the ion count.

!

  question:        5
    section:       1
    line_1:        This test should be run well outside the SAA.
    line_2:        The test is to be done once in Cycle 4.
    line_3:        Execute after successful completion of 5273 and before 5275.
    line_4:        Program can be executed PRIOR to the COSTAR/GHRS deplyoment.

  question:        5
    section:       2
    line_1:        This is an internal test and does not require any special pointing of the
    line_2:        telescope. This test does not require the HRS to be the prime SI.
    line_3:        There is no target list with this proposal.

!

  question:        7
    section:       1
    line_1:        1. The science data will be reduced offline to generate new thresholds.
    line_3:        The load threshold command blocks in project database will be updated with the
    line_4:        new thresholds.
