Session Notes for R1 (Rapid Turnaround Monday) session: r1950 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2020.html#r1 for the session purpose. =========================================================== ----- Parameter listing -------------------------------------- Experiment: R1950 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2020-160-17:00:00 End: 2020-161-17:00:00 Current yyyyddd: 2020160 (2020.44) ( 19009 MJD, MON. 8JUN.) Greenwich sidereal time: 10:10:09 (17:00:00 UT) Sun's RA and DEC: 5h 9.4m 22d 55.5 =========================================================== Important Station Information Ny Alesund-South was tagged along to this schedule file. Wettzell-North's SEFDs were increased to 4200 for X-band and 2100 for S-band to compensate for the warm receiver. =========================================================== 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 Ht Is Kk Ma Ny Ns Kv Wn Wz Yg 0059+581 20160-170000| 96 68 48 71 23 60 110 110 | 1057-797 20160-170000| 82 82| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ht Is Kk Ma Ny Ns Kv Wn Wz Yg 2335-027 20161-165441| 222 222 202 | 1057-797 20161-165632| 82 82| 1606+106 20161-165635| 36 61 61 | NRAO512 20161-165818| 97 97 37 97 | 1741-038 20161-165904| 51 51 51| =========================================================== SKED Summary from file ./r1950.skd for experiment R1950 (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 = 110.8 (Baseline Is-Ma on 0606-223) RMS = 11.1 Total time: 1440 minutes ( 24.0 hours).
