Session Notes for R1 (Rapid Turnaround Monday) session: r1871 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: R1871 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2018-337-17:00:00 End: 2018-338-17:00:00 Current yyyyddd: 2018337 (2018.92) ( 18456 MJD, MON. 3DEC.) Greenwich sidereal time: 21:49:53 (17:00:00 UT) Sun's RA and DEC: 16h 39.8m -22d 9.3 =========================================================== Important Station Information Kokee will run with a warm receiver for this session so the SEFDs for Kokee was increased to 6000 for X-band and 1500 for S-band. The elevation limits for Ny Alesund was increased to 12 degrees for this session. =========================================================== There are no observations for Kokee from 18:15 U.T. to 19:45 U.T. Kokee will participate in the intensive session during this period. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Ag Ht Is Kb Ke Kk Ny Kv Yg 0454-234 18337-170000| 78 108 43 108 93 83| 1502+106 18337-170000| 137 137 | 0552+398 18337-170241| 151 43 147 135 151| 2215+150 18337-170253| 299 288 299 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ag Ht Is Kb Ke Kk Ny Kv Yg 3C446 18338-165341| 56 56 | 0823+033 18338-165438| 109 70 295 295 | 0017+200 18338-165528| 43 43 | 2355-106 18338-165707| 168 168| 1149-084 18338-165708| 167 167 167 | =========================================================== SKED Summary from file ./r1871.skd for experiment R1871 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 7.9 Min = 0.0 Max = 65.5 (Baseline Ag-Yg on 0727-115) RMS = 12.6 Total time: 1440 minutes ( 24.0 hours).
