; ; This file contains the UVCS CRUISE PHASE TIME-LINE ; Time-line has the required format: TIME # ACTION # COMMENT ; Time has the format: ddd & hh:mm ; The type of commanding (dedicated/shared) is in paretheses, in the COMMENT ; The purpose of this is to make the file machine readable for ; input to the SOHO timeline IDL program ; Blank lines and comment lines -- preceeded by ";" -- are ignored ; Notes: ; ----- ; ; The following timeline consists of a deployment period, ; which runs from Day 4 through Day 86; a preliminary observation ; period, which runs from Day 87 through spacecraft commissioning, ; which is expected to end TBD days after Halo orbit insertion; ; and science operations, which begins after the completion of ; spacecraft commissioning (the first day of science operations ; is designated C1 etc.). Beginning on day 87, the UVCS ; timeline is based on a standard format of seven ; observing periods. The start and end times of the periods are ; the following: ; Period 1: 01:24 to 02:42 First contact period ; Period 2: 02:42 to 06:42 Non-contact period ; Period 3: 06:42 to 11:36 Second and part of third contact period ; Period 4: 11:36 to 16:00 Part of third contact period ; Period 5: 16:00 to 20:00 Non-contact period ; Period 6: 20:00 to 21:18 Fourth contact period ; Period 7: 21:18 to 01:24+1d Non-contact period ; ; The timeline for day 87, which can be found below, provides a ; an example of a typical day which follows the standard format. ; ; Periods 1,3, and 6 are normally used for standard ; synoptic observations which are repeated during the mission. ; Preliminary synoptic observations are planned to commence on day 87 ; and continue through day 91. They will be interrupted for four ; days (i.e., 92 - 95) for UVCS flat field calibration, and again ; for five days (i.e., 115 - 119) for Halo orbit injection. UVCS ; requests that the synoptic observations continue from Day 120 and ; throughout the mission. UVCS also requests to participate in ; intercal JOP's on days 120 and 121 during UVCS obserrving ; period "4". UVCS requests synoptic observations during UVCS ; observing periods 1, 3, and 6 from day 122 until the end of ; spacecraft commissioning; UVCS would not observe during other ; observing periods on those days. ; ; UVCS observing periods 2, 5 and 7 are used for various scientific ; observations starting on day 87 with the indicated interuptions. ; Currently, there are no plans to roll UVCS during these periods. ; These periods could also be used for JOP's providing the JOP's ; were compatible with certain target selection limitations due to ; available roll ranges. ; ; UVCS period "4" would be used for various purposes prior to ; day C1, and thereafter, would then be used for JOP's (as a priority) ; and also other purposes. ; ; The first UVCS observations, which are expected to produce results ; suitable for a press release, are planned for day 87. ; The following are some additional notes regarding this timeline. ; ; - This timeline is a preliminary draft and subject to change ; - This timeline is for nominal operation only ; - Most deployment activities completed during TTP ; - Preliminary observations and calibrations during TTP ; - Commands are sent from IWS unless otherwise noted ; - All operations prior to day 87 performed during contact periods ; (It is assumed that longest real-time period is from 08:00 to 16:00) ; - SMOCC updates LOBT daily at start of long contact period. ; - IWS commanding uses BINARY format (see EOF ICD). ; - B-side electronics used only in case of failure of A-side ; - need to verify MOM launch configuration (2.7 solar radii) ; - Verify ESR flag does NOT close aperture door ; - Calibration status of T monitors? ; - It is assumed to fully open the aperture door prior to ; deployment of roll/pointing, so to have accurate ; Sun Sensor signals (not through window in door). ; - Disk obs. (i.e., Intercal JOP's) in TTP are TBC. ; - Closing of aperture door during S/C thruster operations is TBD ; (ESA is to determine if this is necessary). ; - During S/C operations UVCS is in Setup 2 Mode ; (i.e., XDL detector power ON, but all detectors HV OFF). ; - State of Detector HV during rolls is TBD ; ___________ ; | | ; | TIME-LINE | ; |___________| ; 1) Initial switch ON (takes 3 days) ; This activity starts during S/C commissioning and outgassing ; (i.e., at least 4 days after injection into transfer trajectory. ; See SOHO time-line, August 94, 1994, by P.C.H.
