Session Notes for rd0903 Prepared by J. Gipson, NVI, Inc./GSFC =========================================================== PURPOSE AND GENERAL NOTES =========================================================== The purpose of this rd0901 is to determine the positions of some sources that do not have good positions. This is in preparation for the next version of the ICRF, which is used in geodesy and astrometry. Many of these sources are very weak. Because of this, the integration time is long, and the number of observations is lower than normal. This session must be recorded on Mk5 disks. =========================================================== ----- Parameter listing -------------------------------------- Experiment: RD0903 Description R&D-03 2009 Scheduler: NASA Correlator: HAYSTACK Start: 2009-049-18:00:00 End: 2009-050-18:00:00 Current yyyyddd: 2009049 (2009.13) ( 14881 MJD, WED. 18FEB.)
