It is clear line_17: that all channels which exceed spec continually or line_18: intermittently should be turned off. Even though we have line_19: much information from ground-based tests, those data, taken at line_20: room temperature, may have listed as good channels which will line_21: be bad at operating temperatures. There may also be channels line_22: which are noisy on the ground that will be good under line_23: operating conditions. ! question: 3 section: 2 line_1: These channels could improve either because the temperature line_2: is lower or because the (intermittent) noise was due to line_3: interference from something in the environment which will line_4: not be present on orbit. For this reason, all channels line_5: should be enable for these DARK observations. Because of the line_6: intermittent nature of the noise in the channels (some bad line_7: channels showed up in only one or two of 10 or 20 darks), it line_8: is imperative to have as many DARKs as possible in SV. line_10: The parameters specified for the DARK exposures should result line_11: in the following values for FOS parameters: line_13: livetime = 0.500 line_14: deadtime = 0.010 line_15: ints = 40 line_16: patterns = 1 line_19: The photocathode will be sdampled at half-diode-height line_20: intervals over the YBASE range from -1472 to +1472, which line_21: encompasses all normal science image locations. ! question: 5 section: 1 line_1: Observations are desired at high and line_2: low Geomagnetic latitudes. line_7: OV/SV prerequisites: line_8: completion of all OV activities line_10: If possible, schedule the exposures up to 90 minutes in line_11: length. Don't schedule the exposures for less than 30 minutes. line_13: Minimum/Delta Plan Designations: line_14: All DARK observations of minimum plan. line_17: For all DARK observations, ALL CHANNELS should be enabled. ! question: 5 section: 2 line_1: It is important to have as many of the DARKs done as early as line_2: possible, because the list of disabled diodes should be line_3: determined before any of the calibration exposures are taken. line_4: For example, any flat field with sub-stepping and overscan line_5: will be WRONG, in a manner that is not easily correctable, if line_6: a diode is turned off after the calibration exposures. As a line_7: secondary consideration, it may be possible to "fix" some line_8: bad diodes by varying the discriminator settings; clearly line_9: clearly this requires early and often DARKs. line_11: For this reason, the first 4 hours of DARKs on each side line_12: (lines 5.00-5.07 for the RED, lines 5.50-5.57 on the BLUE), line_13: must be scheduled early in SV. These 8 hours of DARKs must line_14: be completed at least 7 days prior to the external line_15: calibrations obtained in proposals 1315, 1317, 1318, 1319, line_16: 1320, and 1430. line_17: If it is possible to line_18: to schedule more than 8 hours of DARKs in early SV, please do line_19: so. However, no more than 20 hours of DARKs should be obtained. ! question: 6 section: 1 line_1: This test is not stray light sensitive. 40 hours of observation is internal line_2: dark measurements. ! question: 7 section: 1 line_1: Data reduction will be performed at the ST ScI, and the analysis will be line_2: performed using FOS IDT computer facilities. Although this is a calibration, no line_3: data will need to be added to the PODPS pipeline. ! question: 10 section: 1 line_1: Data analysis, research assistant support, and funding will be provided under line_2: NASA's FOS GTO contract(s). ! !end of general form text general_form_address: lname: BAITY fname: BILL category: PI inst: U.C., SAN DIEGO addr_1: CASS DEPARTMENT, C-011 city: LA JOLLA state: CA zip: 92093 country: USA ! ! end of general_form_address records !
