This measurement line_5: is followed by 10 PC KSPOT exposures with the pyramid line_6: in the WFC configuration. Each KSPOT is separated by 30 line_7: minutes and the entire time series will be analyzed line_8: offline to characterize the evolution of ice if present. line_9: Real-time down link of a subset of the science data line_10: is needed in order to assess icing and make a decision line_11: to intervene with subsequent WFPC activities. line_12: A real-time uplink opportunity is required to occur line_13: at a maximum of 6 hours after the last KSPOT exposure. ! question: 5 section: 1 line_1: Real-time down link of a subset of the science data line_2: is needed in order to assess icing and make a decision line_3: to intervene with subsequent WFPC activities. line_4: A real-time uplink opportunity is required to occur line_5: at a maximum of 6 hours after the last KSPOT exposure. line_6: The real-time uplink will be used to intervene by line_7: turning the TECs off or SAFE the WFPC. The uplink line_8: activities will be performed by the MOC. line_10: WFC1480 must follow WFC2792, Hi-temp Decontamination, line_11: by a minimum of an orbit (to wait for cooling after the line_12: bake-out) and a maximum of 12 hours to ensure that line_13: the contaminants are minimized. Additionally, line_14: any other WFC activity should follow this test by line_15: no less than a week in order to study the data and line_16: plan for contingency in the event ice is found. ! question: 7 section: 1 line_1: ! question: 8 section: 1 line_1: ! !end of general form text general_form_address: lname: DANIELSON fname: G. mi: E. category: CON inst: CALTECH addr_1: DIVISION OF GEOLOGICAL & PLANETARY SCIENCES city: PASADENA state: CA zip: 91125 country: USA phone: (818) 356-6861 ! lname: WESTPHAL fname: JAMES mi: A. category: PI inst: CALTECH addr_1: DIVISION OF GEOLOGICAL & PLANETARY SCIENCE city: PASADENA state: CA zip: 91125 country: USA phone: (818) 356-4900 ! lname: GUNN fname: JAMES mi: E. category: CON inst: PRINCETON UNIVERISITY addr_1: ASTROPHYSICAL SCIENCE addr_2: PEYTON HALL city: PRINCETON state: NJ zip: 08540 country: USA phone: (609) 452-3802 ! lname: GALLAGHER fname: DAVID category: CON inst: STSCI addr_1: 3700 SAN MARTIN DR. city: BALTIMORE state: MD zip: 21218 country: USA phone: (301) 338-4834 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: A+81266 descr_1: UV SPECTROPHOTOMETRIC STANDARD pos_1: RA= 09H21M29S +/-1S, pos_2: DEC= 81D43'00" +/-10", equinox: 2000 fluxnum_1: 1 fluxval_1: V=12.1 +/-0.5 ! ! end of fixed targets !
