These tests were defined line_3: in proposal 1457, in which total exposure time for each line_4: detector is approx. 92 minutes. We had expected the test line_5: to be run every time HV was turned on, and that this line_6: would happen perhaps 3 or 4 times. As it now appears that line_7: HV may be cycled on and off many times, we defined this line_8: abbreviated test to check the detector calibrations line_9: frequently, but perform the full test only 4 times total. This line_10: will give us confidence in the stability of the detectors, line_11: but will not require an unreasonably large amount of time. ! question: 3 section: 1 line_1: The short test to be run every 14 +/- 3 days includes: line_2: line 1. 70 second dark count measurement line_3: line 2. focus check at nominal HV and tweak line_4: line 3. 28 sec flat field lamp obs at center coords. line_5: lines 4-7. sample mapping function at center Y def. line_6: lines 8-11. line mapping function at center X def. line_8: For D1 43 lines of data, 6.42 min. exp. time line_9: X11 executions = 70.62 minutes 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 four times includes: line_14: line 13. complete PMAP line_15: line 12. complete sample mapping function (MSKSCN) line_16: line 14. complete line mapping function (TOPBOTSCN) line_18: Each execution produces 127 lines of data per detector line_19: D1 exposure time 14.82 min. per execution line_20: X4 executions = 59.27 minutes total 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. After several executions during OV and SV line_4: we will be able to make firm recommendations about the line_5: required frequency of repeats during the GO era. ! 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 4 sequences for scheduling: line_2: S1: Lines 100 - 104 D1 short test line_3: S2: Lines 200 - 204 D2 short test line_5: S3: Lines 300 - 303 D1 long test line_6: S4: 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 100 - 104 and 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: EBBETS fname: DENNIS title: DR. category: PI ! lname: EBBETS fname: DENNIS mi: C title: DR. category: PI inst: BALL AEROSPACE addr_1: PO BOX 1062 addr_2: AR 1 city: BOULDER state: CO zip: 80306 country: USA phone: 303-939-5964 ! ! end of general_form_address records !
