Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2006.html#r1 for the session purpose. =========================================================== Parameter values for experiment R1237 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see the master schedule Nominal start: 2006-228-17:00:00 Nominal end: 2006-229-17:00:00 Current yyyyddd: 2006228 (2006.62) ( 13964 MJD, WED. 16AUG.) Greenwich sidereal time: 14:39:47.00 (17: 0: 0 UT) Sun's RA and DEC: 9h 44.0m 13d 37.4 =========================================================== Important Station Information Ny Alesund was tagged along to this session. Seshan was scheduled to participate in this session. Unfortunately, the antenna orbit needs to be repaired immediately. As a result, the antenna will be down until early November. =========================================================== 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 Observation listing from file ./r1237.skd for experiment R1237 Source Start DURATIONS name yyddd-hhmmss Ho Kk Ma Ny Tc Wf Wz 0537-441 06228-170000| 107 107 | 1053+815 06228-170000| 200 200 72 141| 0955+476 06228-170429| 100 157 100 157 105 93| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ho Kk Ma Ny Tc Wf Wz 1741-038 06229-165319| 40 40 40| 1334-127 06229-165532| 161 200 200 188| NGC1218 06229-165559| 200 200 | =========================================================== SKED Summary from file ./r1237.skd for experiment R1237 (all scans with at least one subnet station) Average number of obs. per baseline per source (normalized by up-time) = 13.2 Min = .0 Max = 2160.0 (Baseline Ny-Wz on 1606+106) RMS = 75.2 Total time: 1439 minutes ( 24.0 hours).
