We will use the normal script mode for the short pulse commands (7 or so expected). SOT(Bill): - Radiation levels low - OTG Telecon went over action items from SW review. Expect to finalize items which affect TRW software development by COB tomorrow, allowing them to proceed with SW development based on firm reviewed requirements. DSOPS(Joy): - One quick look (see below). GOT(Chris: - Will talk to Lockheed this am regarding scripting problem (see note 4) Meetings, etc. - Pass plan review after 9am - FDB at 2pm. 3) Quick look data: Seq # ObsID It Target start time SI Grat Comment ---------------------------------------------------------------------------------------------------------- 390007 01015 00 PKS2155-304 2000:341:15:46:27.501 9.7 ACIS-S LETG LETG dispersion clearly visible. 4) Chris Eagan & Jeff Holms discussed the scripting problem with Lockheed in their normal 10am Thursday telecon. Immediate plan is to get Lockheed technical people in commanding and scripting areas to participate in test activities with OCC. Intent is to demonstrate problem to them and perform diagnostics. Will try to do this today after pass ends at about 12:30pm EST. 5) LETG retaction. The LETG was successfully retracted using CAP 684, Rev C. The retraction required one long pulse and 8 short 128 ms pulses. The last retraction on Nov 18 also required 8 short pulses. The B retract limit switch was detected. We used the single-stepping mode thru those sections of the script which had single commands separated by "WAIT 1" statements. This worked with no problems.
