Greenwich sidereal time: 08:19:45 (17:00:00 UT) Sun's RA and DEC: 3h 16.1m 18d 7.4 =========================================================== Important Station Information Ny Alesund-South was tagged along to this schedule file. The SEFDs for Ny Alesund-South and Wettzell-North were increased to compensate for their warm receivers. =========================================================== 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 Ht Is Kk Ma Ny Ns Kv Wn Wz Yg Zc 0059+581 20132-170000| 160 82 110 73 38 97 160 107 20| 1511-558 20132-170000| 102 102 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ht Is Kk Ma Ny Ns Kv Wn Wz Yg Zc 1144+402 20133-165549| 32 47 75 96 100 100 100 | 3C446 20133-165722| 20 20 | 1144-379 20133-165738| 137 137 | 1308+326 20133-165806| 109 109 109 109| 1908-201 20133-165846| 69 69 69 | =========================================================== SKED Summary from file ./r1946.skd for experiment R1946 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 7.0 Min = 0.0 Max = 54.1 (Baseline Ht-Yg on 1511-558) RMS = 10.2 Total time: 1440 minutes ( 24.0 hours).
