KSC Pass Conflicts and Schedule 5.1 YOHKOH/ASCA/AKEBONO/HALCA Pass Conflicts at KSC: Six (6) Yohkoh passes are lost for week 45. 5.2 Future Schedule: None 6. Special Operations: None 7. Hikitsugi Items: 7.1 Changing of Passwords The RASM password for DSN schedule changes has been changed. The password for account s88239 on the FACOM GS8400/10 was changed on Saturday 01-Nov. 7.2 Bug in op_first_guess SSOC tohbans should be aware of a bug in op_first_guess. When we tried to create the 971028-0723 OP we got this message: "% OP_START_END: Problem with detection of LOS/AOS/DSN Repro Events" We avoided the problem, when using op_first_guess, by responding to "Change any standard op_first_guess options?" by choosing yes, then in response to "Enter BDR optimization (1 or 2), by choosing 1. 7.3 Tohbans for W44 SSOC : Kumagai & Watanabe_Te KSC : Kasahara & Kubo 7.4 OP and Command Sheet Status The command sheets and the OP for Monday (03-Nov-97) have been created and transferred to KSC. 7.5 STT timer setting STT timer setting is due on 10 Nov, Monday. 7.6 Holiday Schedule: The next holiday will be 09 Nov, Sunday. 7.7 OPOGNEW instead of OPOGEDT ----From W37 report ---------------------------- We continued to use the revised version of OPOGEDT, OPOGNEW. OPOGNEW is the same as OPOGEDT except that the printing out of the OP is simpler. The SSOC tohbans should press the PF4 key (`print') on the mainframe and then print out the OP by typing: IDL> print_op CAUTION : The account, `s80670', for FTP transfering OP from main frame is used. This account's password must be changed every month, same as s88239's one. ***** NOTE ******* Similarly, in order to print out the OG, type: IDL> print_ogall IDL> print_ogsel ***** These softwares are not available. See A/I ****** It is also possible to use the mainframe emulator on flare20 instead of the mainframe terminal for some situations: flare20% telnet mainf1 17 s88239 ex op(opognew) PF3 is {Esc}3 PF4 is {Esc}4 etc. 7.8 STT_PLOT ----From W37 report ---------------------------- It is possible to check the STT Tracking by using the routine `STT_PLOT': First make sure you are on the HOME directory of the yohkoh account then type: IDL> stt_plot (,'DD-MM-YY') This will plot a time variation of the STT output signal level. If the STT is working properly, the signal level should stay in between 400--800, and should vary only in the time period set by the timer. See sample plots in the tohban's manual. --------------------------------------------------------------------------- 7.9 Sirius Data Nothing to report. 7.10 Suggestion to DSN selection rule: mail from JPL ----Quoted from the previous week's report --------------------------------- I understand that you access RASM and choose the passes that are made available to you. We would like you to use the Wallops (WFF) passes as much as possible. In other words, if a pass from one of the DSN sites (Goldstone, Madrid or Canberra) can be substituted by a WFF pass, please use the WFF pass and delete the DSN pass, instead of vice versa. Please understand we are not asking you to give up any coverage but if the same coverage can be accomplished by using WFF instead of the DSN, we would like you to do so. (Albert Chang) --------------------------------------------------------------------------- 8. Action Items 8.1 Further software development It would be greatly appreciated if the SSOC tohbans could recommend any software development that they think will save future tohbans time and which improves the reliability of their work. 8.2 Week-35-A/I-1 SSOC tohbans The SSOC tohbans should inspect the horizon maps sent by JPL and think about whether it would be possible to determine whether the acceptable minumum altitude (Is 10 degrees really the best estimate or is less accepatble?). Please refer to Hudson-san for further information. 8.3 Week-37-A/I-1 /Hudson/status open The following IDL softwares do not work well. Hudson-san will fix them. IDL> print_ogall IDL> print_ogsel end of report -------------------------------------------------------------------------------
