Session Notes for R1 (Rapid Turnaround Monday) session: r1479 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2011.html#r1 for the session purpose. =========================================================== ----- Parameter listing -------------------------------------- Experiment: R1479 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2011-108-17:00:00 End: 2011-109-17:00:00 Current yyyyddd: 2011108 (2011.30) ( 15670 MJD, MON. 18APR.) Greenwich sidereal time: 6:45: 0.00 (17: 0: 0 UT) Sun's RA and DEC: 1h 45.2m 10d 52.5 =========================================================== Important Station Information The SEFDs for Tigo were changed from 20,000 to 60,000 at X-band and 15,000 to 30,000 at S-band to compensate for the warm system temperaturs. As a result, Tigo was only scheduled for 26 scans during this session. =========================================================== There are no observations for Wettzell from 18:15 U.T. to 19:45 U.T. Wettzell will participate in the intensive session during this period. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Hh Hb Ny Sv Tc Ts Wf Wz 0748+126 11108-170000| 43 43 43 43 43| 1741-038 11108-170000| 58 58 | 0059+581 11108-170344| 43 43 43 43 43| 0537-441 11108-170417| 48 48 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Hh Hb Ny Sv Tc Ts Wf Wz 0637-752 11109-114633| 385 385 | ... ... 0912+029 11109-165556| 43 43 | 2008-159 11109-165644| 70 70 | 2113+293 11109-165822| 89 89 | 0925-203 11109-165844| 63 63| =========================================================== SKED Summary from file ./r1479.skd for experiment R1479 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 6.6 Min = 0.0 Max = 102.9 (Baseline Ny-Ts on 1351-018) RMS = 11.7 Total time: 1440 minutes ( 24.0 hours).
