Hikitsugi Items ---------------- 8.1 Tohbans for W14 KSC : S.Yasuno & T.Takano SSOC : H.Nakajima & H.Hara 8.2 STT timer setting The next STT timer set is due on the 2nd, April (JST). 8.3 Transmission of OPs It is no longer necessary to confirm the transmission of OP/OG files to KSC by checking the printout on the 3rd floor in B-toh. Instead the time of transmission of the OP/OG files should be noted down. If the SSOC or KSC tohbans notice any failure in transmission of the OP/OG files then it should be reported to Shuto-san and Kosugi-san. 8.4 SXT patrol image dumps A block command `DP BC 8C-05 (hex)' should be executed whenever an SXT Table is uploaded. Since the Sun is very quiet, ARS parameters need to be checked by the SXT patrol images dumped by this command. 8.5 WWW server of DSN The DSN NOCC Information Server (NIS) is now on-line and available for DSN scheduling operations. The URL location is: http://dsn.jpl.nasa.gov/nss But it is not used for operations, so does this item need to be mentioned in the tohban report? 8.6 New works not mentioned in the manual The data corruptions from DSN(JPL) and the re-transmission request logs are put on the directory ~/dsn_corrupt by Katano-san. SSOC Tohbans should check these logs and report the problems. The lists of the Strawman schedules are printed out by Katano-san. ------------------------------- End of Report ---------------------------------
