Session Notes for R&D (Research & Development) session: rd1103 Prepared by C. Thomas, NVI, Inc./GSFC =========================================================== Purpose The purpose of rd1103 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 except Tigo (20 at X-band and 15 at S-band) and Fortaleza (15 at X-band and 12 at S-band). The schedule uses a selection of 120 sources from the good geodetic source list. The minimum subnet size was set to 3. =========================================================== ----- Parameter listing -------------------------------------- Experiment: RD1103 Description R&D-03 2011 Scheduler: NASA Correlator: HAYS Start: 2011-103-18:00:00 End: 2011-104-18:00:00 Current yyyyddd: 2011103 (2011.28) ( 15665 MJD, WED. 13APR.) Greenwich sidereal time: 7:26: 0.00 (18: 0: 0 UT) Sun's RA and DEC: 1h 26.9m 9d 6.7 =========================================================== Important Station Information Fortaleza was tagged along to this schedule file. =========================================================== There are no observations for Kokee and Wettzell from 18:15 U.T. to 19:45 U.T.
