Session Notes for R1 (Rapid Turnaround Monday) session: r1939 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: R1939 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2020-083-17:00:00 End: 2020-084-17:00:00 Current yyyyddd: 2020083 (2020.23) ( 18932 MJD, MON. 23MAR.) Greenwich sidereal time: 05:06:34 (17:00:00 UT) Sun's RA and DEC: 0h 12.9m 1d 24.1 =========================================================== Important Station Information Ny Alesund-South was tagged along to this schedule file. Also the SEFDs for Ny Alesund-South were increased to 4410 for X-band and 3900 for S-bamd because the station will observe with a 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 Ft Ht Ho Is Kk Ma Ny Ns On Wz Ys 0016+731 20083-170000| 154 154 53 65 69 128 79 131 94| 1057-797 20083-170000| 24 24 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ft Ht Ho Is Kk Ma Ny Ns On Wz Ys 0458-020 20084-164553| 105 89 33 105 63| 0955+476 20084-164833| 42 42 24 34 25 42 23| 1324+224 20084-164833| 25 25 | 0738+491 20084-164956| 81 157 119 122 133 157 137| 0016+731 20084-165016| 74 74 | 1306-395 20084-165239| 89 89 | 1039+811 20084-165314| 88 81 65 88 74 88 71| 0131-522 20084-165518| 38 38 | 1300+580 20084-165523| 272 272 272 272 272 272 272| 0920-397 20084-165708| 167 167 | =========================================================== SKED Summary from file ./r1939.skd for experiment R1939 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 11.4 Min = 0.0 Max = 180.0 (Baseline Ho-Ys on 2022-077) RMS = 14.2 Total time: 1440 minutes ( 24.0 hours).
