Session Notes for R1 (Rapid Turnaround Monday) session: r1879 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2018.html#r1 for the session purpose. =========================================================== ----- Parameter listing -------------------------------------- Experiment: R1879 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2019-028-17:00:00 End: 2019-029-17:00:00 Current yyyyddd: 2019028 (2019.08) ( 18512 MJD, MON. 28JAN.) Greenwich sidereal time: 01:30:40 (17:00:00 UT) Sun's RA and DEC: 20h 43.6m -18d 8.5 =========================================================== Important Station Information Katherine was tagged along to this schedule file. The SNRs for the Katherine baselines were decreased 15 for X-band and 13 for S-band so that more scans per hour would be scheduled. =========================================================== There are no observations for Kokee, Wettzell-North, and Wettzell from 18:15 U.T. to 19:45 U.T. Kokee, Wettzell-North, and Wettzell will participate in the intensive session during this period. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Ft Ht Is Ke Kk Ny On Wn Wz Yg 0748+126 19028-170000| 171 73 300 169 157 201 182 300| 1741-038 19028-170000| 43 43 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ft Ht Is Ke Kk Ny On Wn Wz Yg 0104-408 19029-165712| 163 163 | OJ287 19029-165724| 151 151 151 151 151 151| 1351-018 19029-165731| 144 144 | =========================================================== SKED Summary from file ./r1879.skd for experiment R1879 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 7.6 Min = 0.0 Max = 180.0 (Baseline Ft-Ny on 1741-038) RMS = 15.1 Total time: 1440 minutes ( 24.0 hours).
