This gives us confidence in line_5: the stability of the detectors, but will not require an line_6: unreasonably large amount of time. ! question: 3 section: 1 line_1: The short test to be run includes: line_2: 1) 70 second dark count measurement line_3: 2) focus check at nominal HV and tweak line_4: 3) 28 sec flat field lamp obs at center coords. line_5: 4) sample mapping function at center Y def. line_6: 5) line mapping function at center X def. line_10: For D2 43 lines of data, 16.92 min. exp. time line_11: X11 executions = 186.12 minutes line_13: The longer test to be run as needed includes: line_14: 1) complete PMAP line_15: 2) complete sample mapping function (MSKSCN) line_16: 3) complete line mapping function (TOPBOTSCN) line_18: Each execution produces 127 lines of data per detector line_21: D2 exposure time 44.45 min. per execution line_22: X4 executions = 177.80 minutes total ! question: 4 section: 1 line_1: These same calibrations were run several times during line_2: ground based testing in Boulder, and were repeated line_3: during A&V, OV, SV, Cycle 1, and Cycle 2. line_4: Periodic repeats of this proposal are necessary to line_5: ensure the stability of the detectors. ! question: 5 section: 1 line_1: Exposure times were specified based on measured count line_2: rates with the internal flat field lamps, and the line_3: requirement to obtain approximately 10000 counts per line_4: diode. There are no external targets, and no line_5: special pointing requirements. All of these observations line_6: should be scheduled as interleavers. Both the short and line_7: long test contain several exposures. None of the individual line_8: exposures exceeds 12 minutes. I have asked that for each line_9: test its individual components be grouped within 12 hours. line_10: This is not a hard limit, and could be stretched to 16 or line_11: 24 hours if absolutely necessary. ! question: 6 section: 1 line_1: This prop contains 2 sequences for scheduling: line_3: S1: Lines 200 - 204 D2 short test line_6: S2: Lines 400 - 403 D2 long test ! question: 7 section: 1 line_1: Standard reductions and output products will be produced. ! question: 8 section: 1 line_1: For lines 200 - 204 I have requested line_2: "group within 12 hours". The goal is simply to obtain line_3: all of the calibrations while the thermal and electro- line_4: optical properties are constant. ! !end of general form text general_form_address: lname: HULBERT fname: STEPHEN mi: J. title: DR. category: PI inst: STSCI ! ! end of general_form_address records !
