The dark image will determine if the detector line_3: electronics worked correctly and the WAVE exposure will line_4: verify that the FOS optical path is still intact. line_5: As these images will include the first use of the FOS line_6: high voltage after the shuttle portion of the servicing line_7: mission, the data will be taken with real-time telemetry line_8: to ensure that problems are detected immediately. ! question: 5 section: 1 line_1: Both exposures require real-time telemetry throughout the line_2: observation to ensure that problems are detected and line_3: resolved quickly. The order of the observations is important line_4: as the DARK image verifies a subset of the functions that line_5: are verified by the WAVE image. line_7: Prerequisites: line_8: The FOS must have successfully transitioned into the line_9: HOLD configuration and the FOS internal pressure must line_10: have been below 1E-5 torr for a minimum of 12 hours line_11: as defined by the pressure monitoring activity line_12: (proposal 4762) prior to the execution of this proposal. ! !end of general form text general_form_address: lname: FITCH fname: JOHN mi: E. category: PI inst: STSCI addr_1: SESD/ESB addr_2: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA phone: 410-338-4493 ! ! end of general_form_address records !
