Session Notes for R1 (Rapid Turnaround Monday) session: r1962 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: R1962 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2020-244-17:00:00 End: 2020-245-17:00:00 Current yyyyddd: 2020244 (2020.67) ( 19093 MJD, MON. 31AUG.) Greenwich sidereal time: 15:41:19 (17:00:00 UT) Sun's RA and DEC: 10h 41.4m 8d 17.4 =========================================================== Important Station Information Noto was tagged along to this schedule file. Ny Alesund's SEFDs were increased to 3000 for both X-band and S-band because of their warm receiver. Ny Alesund was tagged along to this schedule file because they plan to scan the antenna from August 28 through September 6. =========================================================== 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 Ag Ft Ht Ho Kk Ma Mc Ny On Kv Sv Wz Ys Nt 0019+058 20244-170000| 67 123 123 | 1639-062 20244-170000| 269 269 155 142 148 263 126 163 157 176| 0322+222 20244-170305| 138 153 170 170 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ag Ft Ht Ho Kk Ma Mc Ny On Kv Sv Wz Ys Nt 1124-186 20245-165518| 277 277 71 277 | 1803+784 20245-165606| 95 64 31 229 87 229 20 115 20| 0044-846 20245-165731| 144 144 | 1128+385 20245-165844| 71 71 71 71 71 71 20| =========================================================== SKED Summary from file ./r1962.skd for experiment R1962 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 6.9 Min = 0.0 Max = 232.3 (Baseline Ny-Ys on 1749+096) RMS = 10.9 Total time: 1440 minutes ( 24.0 hours).
