Session Notes for R1 (Rapid Turnaround Monday) session: r11001 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2021.html#r1 for the session purpose. =========================================================== ----- Parameter listing -------------------------------------- Experiment: R11001 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2021-151-17:00:00 End: 2021-152-17:00:00 Current yyyyddd: 2021151 (2021.41) ( 19366 MJD, MON. 31MAY.) Greenwich sidereal time: 09:37:39 (17:00:00 UT) Sun's RA and DEC: 4h 35.4m 22d 0.8 =========================================================== Important Station Information ** This schedule file was remade without Matera. Matera is not participating because there is a serious problem with their azimuth wheel. The wheel will be replaced within the next few weeks.** Ny Alesund-South and Santa Maria were 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 Ag Ht Is Ny Ns Sa Kv Wn Yg 1417+385 21151-170000| 200 200 198 200 200 86 | 1556-245 21151-170104| 200 200| 0642+449 21151-170206| 172 172 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ag Ht Is Ny Ns Sa Kv Wn Yg 1751+288 21152-165402| 149 129 151 195 46 195| 1417+385 21152-165526| 67 67 | 0016+731 21152-165714| 53 52 53 44 26 | 0727-115 21152-165817| 28 20 28 | 0202+319 21152-165848| 67 67 67 67 | 0834-201 21152-165921| 34 34 | =========================================================== SKED Summary from file ./r11001.skd for experiment R11001 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 10.7 Min = 0.0 Max = 78.5 (Baseline Ny-Wn on 2036-034) RMS = 16.4 Total time: 1440 minutes ( 24.0 hours).
