Session Notes for R1 (Rapid Turnaround Monday) session: r1324 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2008.html#r1 for the session purpose. =========================================================== Parameter values for experiment R1324 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see the master schedule. Nominal start: 2008-105-17:00:00 Nominal end: 2008-106-17:00:00 Current yyyyddd: 2008105 (2008.29) ( 14571 MJD, MON. 14APR.) Greenwich sidereal time: 6:32: 0.00 (17: 0: 0 UT) Sun's RA and DEC: 1h 33.1m 9d 43.1 =========================================================== Important Station Information Zelenchuckskaya was tagged along to this schedule file. Ny Alesund's receiver is running warm and should be fixed in about 3 weeks. So, Ny Alesund's SEFDs were adjusted by a factor of 3 in X-band (900 to 2700) and a factor of 2 in S-band (1200 to 2400). =========================================================== 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 Ho Kk Ny Sh Ts Wf Wz Zc 1739+522 08105-170000| 56 82 40 40 82 40 40| 1611+343 08105-170158| 40 40 40 40 40 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ho Kk Ny Sh Ts Wf Wz Zc OJ287 08106-165639| 40 40 40 40| 0607-157 08106-165828| 40 40 | 1958-179 08106-165848| 40 40 40 | =========================================================== SKED Summary from file ./r1324.skd for experiment R1324 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 10.5 Min = 0.0 Max = 180.0 (Baseline Wf-Wz on 1921-293) RMS = 14.3 Total time: 1440 minutes ( 24.0 hours).
