Greenwich sidereal time: 19:04:18 (17:00:00 UT) Sun's RA and DEC: 13h 48.8m -11d 12.2 =========================================================== Important Station Information Kokee's SEFDs were increased to 6000 for X-band and 1500 for S-band because the receiver is running warm. =========================================================== There are no observations for Kokee and Wettzell from 18:15 U.T. to 19:45 U.T. Kokee and Wettzell will participate in the intensive session during this period. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Ft Ht Is Ke Kk Ma Kv Wn Wz Yg 0748+126 18295-170000| 293 284 293| 3C418 18295-170000| 186 80 94 43 183 186 184 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ft Ht Is Ke Kk Ma Kv Wn Wz Yg 0451-282 18296-165338| 164 164| 1749+096 18296-165420| 197 43 145 197 197 | 0322+222 18296-165658| 177 177 | 0131-522 18296-165701| 174 174 | 1806+456 18296-165813| 102 102 | 2318+049 18296-165829| 86 86 | =========================================================== SKED Summary from file ./r1865.skd for experiment R1865 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 5.6 Min = 0.0 Max = 133.3 (Baseline Ft-Kk on 2227-088) RMS = 10.5 Total time: 1440 minutes ( 24.0 hours).
