Session Notes for rd0906 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. This session must be recorded on Mk5 disks. =========================================================== ----- Parameter listing -------------------------------------- Experiment: RD0906 Description R&D-06 2009 Scheduler: NASA Correlator: HAYSTACK Start: 2009-105-18:00:00 End: 2009-106-18:00:00 Current yyyyddd: 2009105 (2009.29) ( 14937 MJD, WED. 15APR.)
