Greenwich sidereal time: 03:29:05 (17:00:00 UT) Sun's RA and DEC: 22h 41.8m -8d 15.3 =========================================================== Important Station Information Ishioka will stop observing at 06 UT on DOY 049 because of power system maintenance. =========================================================== Calibrator Source Information Five calibrator sources were used during this session. The duration of the calibrator sources is 240 seconds. The sources are 1749+096 @ 210135 and 010529; 0727-115 @ 050039; 0133+476 @ 050139; 2255-282 @ 085958; and 0642+449 @ 130247. =========================================================== There are no observations for Kokee and Wettzell from 18:15 U.T. to 19:45 U.T. and 23:15 U.T. to 00:45 U.T. Kokee and Wettzell will participate in intensive sessions during those periods. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Ag Hb Is Ke Kk Ma Kv Wz Yg 0454-234 23058-170000| 86 86 63 | 1255-316 23058-170000| 52 52 52 | 1156+295 23058-170156| 41 41 20 32 | 1057-797 23058-170202| 144 99 147 147| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ag Hb Is Ke Kk Ma Kv Wz Yg 0308-611 23059-165618| 109 200 200| 1803+784 23059-165725| 39 39 20 | OJ287 23059-165739| 20 20 | 0454-234 23059-165848| 72 72 | NRAO512 23059-165855| 65 65 | =========================================================== SKED Summary from file ./r11092.skd for experiment R11092 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 9.0 Min = 0.0 Max = 83.1 (Baseline Ag-Kk on 0727-115) RMS = 13.7 Total time: 1440 minutes ( 24.0 hours).
