Session Notes for R1 (Rapid Turnaround Monday) session: r1861 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: R1861 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2018-268-17:00:00 End: 2018-269-17:00:00 Current yyyyddd: 2018268 (2018.73) ( 18387 MJD, TUES 25SEP.) Greenwich sidereal time: 17:17:51 (17:00:00 UT) Sun's RA and DEC: 12h 9.5m -1d 1.5 =========================================================== Important Station Information Kokee will be running warm during this session. So the SEFDs were increased by a factor of three for X-band and a factor of two for S-band. =========================================================== 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 Ft Ht Is Ke Kk Ma Ny Wz Yg 2227-088 18268-170000| 126 43 73 52 126 73| OJ287 18268-170124| 43 43 | 1057-797 18268-170202| 300 300| 0805+410 18268-170301| 63 63 | 1726+455 18268-170323| 216 278 216 235 278 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ft Ht Is Ke Kk Ma Ny Wz Yg 1639-062 18269-165301| 228 223 228 | 1057-797 18269-165324| 136 136| OJ287 18269-165530| 43 43 43 | 2052-474 18269-165621| 214 214| 1606+106 18269-165730| 145 145 145 145 | 0552+398 18269-165742| 133 133 | =========================================================== SKED Summary from file ./r1861.skd for experiment R1861 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 5.5 Min = 0.0 Max = 106.7 (Baseline Ft-Kk on 2227-088) RMS = 10.7 Total time: 1440 minutes ( 24.0 hours).
