Session Notes for RD1104 Prepared by D. Behrend, NVI, Inc./GSFC =========================================================== PURPOSE AND GENERAL NOTES =========================================================== The purpose of rd1104 is to test 512 Mbps recording mode as the anticipated mode for CONT11. This frequency setup uses 2-bit sampling with no fanout and 32 tracks. The schedule was generated using SNRs of 20 at X-band and 15 at S-band for all stations. All stations have been fully scheduled; TIGO and WARK12 have been given extra weight. The schedule uses a selection of 120 sources from the good geodetic source list. The minimum subnet size was set to 3. Kokee and Wettzell will observe INT I11172 during the time from 1815 UT to 1945 UT. Hobart, Katherine, and Yarragadee should run DRUDG with: rack=none, recorder=Mark 5B =========================================================== Experiment: RD1104 Description R&D-04 2011 Scheduler: NASA Correlator: HAYS Start: 2011-172-17:30:00 End: 2011-173-17:30:00 Current yyyyddd: 2011172 (2011.47) ( 15734 MJD, TUES 21JUN.)
