The sky data will be obtained at high galactic line_4: latitude, low galactic latitude, and in the ecliptic plane, line_5: to determine if there are any differences in the sky line_6: spectrum. These observations will allow us to determine when line_7: sky measurements will be required for science data. Some sky line_8: observations will be read from two different portions of the line_9: photocathode, to check if the dark count is position line_10: dependent. If it is not, then normal science dark measurements line_11: can be obtained by changing the y-base, rather than closing line_12: the entrance aperture, thus allowing for more efficient observing. line_14: The dark measurements will be obtained with a variety of SIs line_15: prime, to test for any EMI problems, and during SAA passages, line_16: to determine if science observations are possible during this line_17: period. Because these parallel observations require very line_19: complicated scheduling and commanding, we do not know how line_20: much of the SV program will have been completed by the end of SV. ! ! end of abstract general_form_proposers: lname: HARTIG fname: GEORGE inst: STSCI country: USA ! lname: KINNEY fname: ANNE inst: STSCI country: USA ! lname: BHATTACHARYA fname: BIDUSHI inst: STSCI country: USA ! lname: BOHLIN fname: RALPH inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! lname: FORD fname: HOLLAND inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: In this test, we will obtain data on the sky and dark backgrounds. Sky line_2: measurements will be obtain at high galactic latitude, low galactic latitude, line_3: and the ecliptic plane, using the low dispersion gratings and the prism. Both line_4: detectors will be used, and data read from two different positions on the line_5: photocathode. The observations will be repeated as often as possible. line_7: Dark measurements will be obtained using both detectors. line_8: Data will be obtained with a variety of SIs prime, to test line_9: for an EMI problems, and data will be taken inside the SAA, line_10: to see if it may be possible to observe in this area. The line_11: 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 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. 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: All observations are parallel. We would like some of the dark measurements to line_2: be obtained in the SAA. For the sky measurements, one must be careful not to line_3: place a bright star (V~8) in the FOS aperture. However, the probability of this line_4: occurring is small (~10 {supered -7}), so the scheduling constraint is not line_5: great. line_7: If possible, schedule the exposures up to 90 minutes in line_8: length. Don't schedule the exposures for less than 30 minutes. line_10: For all DARK observations, ALL CHANNELS should be enabled. ! 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 and analysis will be performed at the ST ScI. ! !end of general form text general_form_address: lname: HARTIG fname: GEORGE category: PI inst: STSCI addr_1: 3700 SAN MARTIN DR. city: BALTIMORE state: MD zip: 21218 country: USA ! ! end of general_form_address records !
