Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2007.html#r1 for the session purpose. =========================================================== Parameter values for experiment R1297 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see the master schedule Nominal start: 2007-282-17:00:00 Nominal end: 2007-283-17:00:00 Current yyyyddd: 2007282 (2007.77) ( 14383 MJD, TUES 9OCT.) Greenwich sidereal time: 18:11: 0.00 (17: 0: 0 UT) Sun's RA and DEC: 12h 59.0m -6d 18.1 =========================================================== Important Station Information This session has mixed bandwidths since Fortaleza is included. Fortaleza is using 4 MHz. Please note that Fortaleza received the 15 VCs from Haystack prior to this session. This schedule file was posted before the VCs were fully tested at Fortaleza. Ny Alesund was tagged along to 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 Ft Hh Ho Ny Tc Ts Wf Wz 0727-115 07282-170000| 40 40 40 | 1611+343 07282-170141| 200 106 91 200 108 85| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ft Hh Ho Ny Tc Ts Wf Wz 2052-474 07283-165519| 109 200 200 | 2356+385 07283-165623| 44 44| 1156+295 07283-165807| 41 45 45| 1921-293 07283-165908| 40 40 | =========================================================== SKED Summary from file ./r1297.skd for experiment R1297 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 8.6 Min = 0.0 Max = 96.0 (Baseline Hh-Tc on 1611+343) RMS = 12.7 Total time: 1440 minutes ( 24.0 hours).
