Hikitsugi Items 7.1 Tohbans for week 14 SSOC: T. Kosugi, R. Haga KSC: K. Shinoda, H. Kozu 7.2 STT timer setting STT timer setting is due on Tuesday, 30-Mar-99 (JST) 7.3 Holiday Schedule The next holiday will be 4-Apr (JST) in week 14. ====== The following is the same as the previous week's report. ====== 7.6 Manual and Checksheet A new version of the English Tohban Manual was generated during the week, along with a corresponding new Tohban Checksheet. The new (and all future) Tohbans are requested to note any changes or mistakes in the manual, and to notify A. Sterling of the changes. If the changes involve the DSN procedures or the ~yohkoh/wallops/README file, Hugh Hudson san should also be notified. Please include your name (or initials) next to your suggested corrections. Current Version Yohkoh Tohban Duties Manual Rev. 1-Feb-99, A. Sterling README (Manual for Wallops/DSN Operations) Ver.5.2 28-Sep-98, H. Hudson The Japanese SSOC Tohban Manual was last modified on 23-Nov-98 by Ishii and Ichimoto san-tachi. 7.7 Some Problems in OP_FIRST_GUESS - NASA tracking passes Hudson san has modified DSN_INPUT.PRO to take care of an op_first_guess problem in picking up some NASA passes occurring near 0 hours UT (see week 98_37 SSOC report for a detailed description of the problem). All seems to be fine now, but for a while Tohbans should double check that all the passes assigned to us by NASA in the latest final schedule are actually included in the OP. - Maximum Elevation In determining zenith passes, Tohbans should use the maximum altitude listed in the Weekly Visible Diagram, rather than the value on the command sheets. (See week 99_04 SSOC Tohban report for more details). 7.8 DSN Pass Additions (from week48_98 report) Pass addition requests can now conveniently be made (preferably at the Preliminary Schedule stage) using the add_dsn routine. See the wallops directory README file, and the Tohban Manual section on DSN Scheduling. ---------------------------------------------------------------------------- 8. Action Items 8.1 Further software development. Status CONTINUING. 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-48-A/I-1 /Hudson/status AJAR. PRINT_OGALL still does not work well. Hudson will fix it. === END ===
