question: 3
section: 1
line_1: Dark measurements will be obtained using both detectors.
line_11: The observations will be repeated as often as possible.
line_13: Although the DARK measurements will be used to determine the
line_14: average level of dark counts to subtract from the science
line_15: data, the primary purpose of the SV (and OV) DARKs is to
line_16: determine which FOS channels should be disabled. 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).
