Session Notes for R1 (Rapid Turnaround Monday) session: r1502 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: R1502 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2011-283-17:00:00 End: 2011-284-17:00:00 Current yyyyddd: 2011283 (2011.78) ( 15845 MJD, MON. 10OCT.) Greenwich sidereal time: 18:15: 0.00 (17: 0: 0 UT) Sun's RA and DEC: 13h 2.8m -6d 41.6 =========================================================== Important Station Information Yarragadee was scheduled as a regular station in this session because the station only picked up one scan per hour when it was tagged along to the schedule file. A test was done to compare the simulated EOP results of a schedule made with Yarragadee and then removed with a schedule made without Yarragadee. The results are as follows: Database X offset/rate Y offset/rate UT1 offset/rate Nutation Psi/Eps $11OCT10NY 45.44 131.97 52.25 128.05 2.07 5.57 95.20 29.80 $11OCT10YR 45.67 139.77 52.91 140.58 2.13 5.60 101.10 31.80 NY: Made without Yarragadee YR: Made with Yarragadee and then removed =========================================================== There are no observations for Wettzell from 18:15 U.T. to 19:45 U.T.
