PLAN ---- Run under control of P8b load Plan for P9 HRC activities EVENTS ------ 18:50 LOS 00:01 AOS - current OBSID 1236 01:23 ACIS stop science 01:26 OBSID 1101 01:30 SIM focus at -369 01:38 ACIS start science NOTES/ISSUES/PROBLEMS --------------------- At shift start we are AOS with OBSID 1100. In planning for the P9 load it was discovered that the target selected for the HRC-I plate focus measurements (HR 1099) could not be scheduled to occur during the required real-time pass because the moon was too close. AR Lac was selected as a replacement. Other efforts in planning the P9 load were to specify SIM offsets and DITHER parameters so that any potential ground commanded adjustments would not compromise the plans for the load and so the load would not undo ground commanded improved focus adjustments. This was done by making slight adjustments, as required to SIM offset and dither parameters: A focus adjustment can be made in real-time and if the OFLS sees that the next observation is at the same focus location it will not include commands to change it but if one wants the focus to go back the OFLS can be given a point that is one motor step different and it will put the commands in the load. For the HRC real-time commanding activities we have drafts for the following CAPs: 351 - Configure HRC for Initial Observations 352 - Adjust SIM Focus Position 353 - Release HRC Shutters from Launch-locks 354 - Set Dither Amplitude 355 - Scan HRC Shutters P9 OR list schedules OK but with OFLS 7.1 (needed to get the correct fid-light locations when the SIM is offset in translation) some of the longer maneuvers are expected cause problems. There is also a problem with scheduling the last four ORs in the load to occur at the perigee passage, as they are behind the earth. FOT-MP will put in a maneuver to away and back (possibly to the north celestial pole?).
