Greenwich sidereal time: 19:53:39 (17:00:00 UT) Sun's RA and DEC: 14h 37.2m -15d 21.2 =========================================================== Important Station Information Ny Alesund-South was tagged along to this schedule file. Ny Alesund's SEFDs were increased to 3000 for both bands to compensate for their warm receiver. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Ft Ht Ma Ny Ns Kv Wn Yg 2227-088 20308-170000| 125 145 81 187 187| 3C418 20308-170353| 151 298 152 305 306 151 306 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ft Ht Ma Ny Ns Kv Wn Yg 0537-441 20309-165132| 395 395| 2113+293 20309-165149| 164 179 156 181 181 | 2215+150 20309-165531| 264 264 264 264 264 264 | =========================================================== SKED Summary from file ./r1971.skd for experiment R1971 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 19.8 Min = 0.0 Max = 450.0 (Baseline Ft-Ht on 3C418 ) RMS = 39.2 Total time: 1440 minutes ( 24.0 hours).
