Session Notes for R1 (Rapid Turnaround Monday) session: r1221 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2006.html#r1 for the session purpose. =========================================================== Parameter values for experiment R1221 Experiment description: IVS-R1 Scheduler: NASA Correlator: Please see master schedule Nominal start: 2006-114-17:00:00 Nominal end: 2006-115-17:00:00 Current yyyyddd: 2006114 (2006.31) ( 13850 MJD, MON. 24APR.) Greenwich sidereal time: 7:10:19.00 (17: 0: 0 UT) Sun's RA and DEC: 2h 8.5m 12d 58.7 =========================================================== Important Station Information Zelenchukskaya was tagged along to this session. Since Seshan has only 8 BBCs, there are only 4 being used at X and 4 being used at S. A total of 9 channels are being recorded because one of the X-band converters is used for both upper and lower sideband. This session has mixed bandwidths since Fortaleza is included. Fortaleza is using 4 MHz. =========================================================== Simulation Results Database X offset/rate Y offset/rate UT1 offset/rate Nutation Psi/Eps $06APR24ZZ 45.98 125.16 44.29 122.98 2.53 7.40 78.50 36.90 =========================================================== There are no observations for Wettzell from 18:15 U.T. to 19:45 U.T.
