EPHIN geom is small, and rates are high. Radmon disabled. NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three nominal supports in last 24 hours, SSR dumps are current, onboard loads good through 280:16:00. One more segment needed to complete this week. OCT0301C email review revealed no problems. Load review today at 1pm, is expected to approve this load GRETA 1.1.1 has been installed on OCC machines. There was a tagup meeting yesterday on the bright star hold investigation. Dan Shropshire emailed the resulting action items and notes (see /pool14/chandra/IRU/gyro_tagup_actions.txt on HEAD network). Quick look data: no new quick look this shift. ------------------------------------------------------- Dan Schwartz, MS #3 das@head-cfa.harvard.edu phone: (617)495-7232 FAX: (617)495-7356 cell phone: (617)512-5627 pager: 877-693-7198 PIN 693-7198 or e-mail 6937198@archwireless.net -------------------------------------------------------
