Hikitsugi Items ---------------- 8.1 Tohbans for W21 KSC : Watanabe ,Hashizume SSOC : Shinohara, Takahasi 8.2 STT timer setting The STT timer should be set during pass 2 on 28-May (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 This is an additional means of checking the final schedule. The automatic ftp system works very well, and using tail_dsn one can confirm the DSN schedule without using either RASM or the Web. 8.6 New works not mentioned in the manual Information about corrupt data 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. 8.7 The RASM script, krasm, now works on flare20 and not flare11. 8.8 The paper feed on the fax machine gave trouble a couple of times. Users should stand by to be sure.
