Session Notes for R1 (Rapid Turnaround Monday) session: r1873 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: R1873 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2018-351-17:00:00 End: 2018-352-17:00:00 Current yyyyddd: 2018351 (2018.96) ( 18470 MJD, MON. 17DEC.) Greenwich sidereal time: 22:45:05 (17:00:00 UT) Sun's RA and DEC: 17h 41.3m -23d 22.0 =========================================================== Important Station Information The SEFDs for Kokee were increased to 6000 for X-band and 3000 for S-band because Kokee will be obseerving with a warm receiver. Santa Maria was tagged along to this schedule file. =========================================================== There are no observations for Kokee, Wettzell, and Wettzell-North from 18:15 U.T. to 19:45 U.T. Kokee, Wettzell, and Wettzell-North will participate in the intensive session during this period. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Ft Is Kb Ke Kk Mc Ny On Wn Wz Yg Sa 0059+581 18351-170000| 252 252 229 43 99 76 122 110 43| 0727-115 18351-170000| 43 43 43 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ft Is Kb Ke Kk Mc Ny On Wn Wz Yg Sa 0202+149 18352-165735| 140 140 | 0119+041 18352-165744| 131 131 131 131 99| 0727-115 18352-165825| 90 90 90 | 0059+581 18352-165831| 84 84 | =========================================================== SKED Summary from file ./r1873.skd for experiment R1873 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 5.9 Min = 0.0 Max = 180.0 (Baseline Ft-Ny on 1741-038) RMS = 12.0 Total time: 1440 minutes ( 24.0 hours).
