Session Notes for R1 (Rapid Turnaround Monday) session: r1941 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: R1941 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2020-097-17:00:00 End: 2020-098-17:00:00 Current yyyyddd: 2020097 (2020.27) ( 18946 MJD, MON. 6APR.) Greenwich sidereal time: 06:01:46 (17:00:00 UT) Sun's RA and DEC: 1h 4.0m 6d 48.8 =========================================================== Important Station Information Ny Alesund-South was tagged along to this schedule file. Ny Alesund-South will observe with a warm receiver, so the SEFDs for Ny Alesund-South were increased to 4410 for X-band and 3900 for S-band. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Bd Ft Ht Is Ma Ny Ns Wn Yg Zc 0955+476 20097-170000| 41 124 124 103 28 67 25 20| OJ287 20097-170106| 92 67 92 | 1149-084 20097-170304| 24 72 172 172 82 54| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Bd Ft Ht Is Ma Ny Ns Wn Yg Zc OJ287 20098-163803| 31 84 65 90 41 99 99 20| 1123+264 20098-164023| 77 400 400 392 400 400 69| 1243-072 20098-164343| 98 98 78| 0955+476 20098-164801| 43 47 117 70 110 117 20| 0529+483 20098-164934| 82 82 | 0716+714 20098-165039| 26 111 80 48 111 20| 1244-255 20098-165223| 56 56 | 1849+670 20098-165311| 162 82 106 57 162 70| 0537-441 20098-165441| 56 56 | 1759-396 20098-165519| 120 120 | 0202+319 20098-165634| 33 52 52 20| 0308-611 20098-165642| 72 72 | 1657-261 20098-165755| 120 120 | 0133+476 20098-165807| 30 108 48 108| 0131-522 20098-165841| 74 74 | NRAO150 20098-165936| 19 19 | =========================================================== SKED Summary from file ./r1941.skd for experiment R1941 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 9.9 Min = 0.0 Max = 205.7 (Baseline Ht-Yg on 0955+476) RMS = 12.6 Total time: 1440 minutes ( 24.0 hours).
