Session Notes for RD1101 Prepared by D. Behrend, NVI, Inc./GSFC =========================================================== PURPOSE AND GENERAL NOTES =========================================================== The purpose of rd1101 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 25 at X-band and 20 at S-band for all stations but TIGO. Baselines with TIGO have SNR targets of 15 and 12, respectively. All stations have been fully scheduled, with an extra weight for TIGO. The schedule uses a selection of 150 sources from the good geodetic source list. Kokee and Wettzell will observe INT I11053 during the time from 1815 UT to 1945 UT. =========================================================== Experiment: RD1101 Description R&D-01 2011 Scheduler: NASA Correlator: HAYS Start: 2011-053-17:30:00 End: 2011-054-17:30:00 Current yyyyddd: 2011053 (2011.15) ( 15615 MJD, TUES 22FEB.)
