Session Notes for RD1309 Prepared by C. Thomas, NVI, Inc. ============================================================================= PURPOSE AND GENERAL NOTES ============================================================================= The purpose of rd1309 is to test 512 Mbps recording mode as the anticipated mode for CONT14. 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. The schedule uses a selection of 60 sources from the good geodetic source list. The minimum subnet size was set to 2. Kokee and Wettzell will observe INT I13310 during the time from 1815 UT to 1945 UT. ============================================================================= ----- Parameter listing -------------------------------------- Experiment: RD1309 Description CONT14 CHECKOUT Scheduler: NASA Correlator: HAYS Start: 2013-310-18:00:00 End: 2013-311-18:00:00 ---------- Scan length parameters------------------------------- VScan Y (Compute scan length) Duration 196sec (default duration) Minscan 43sec (min scan length) Maxscan 600sec (max scan length) Calibration 10sec (time before obs) Early 0sec (start recording) Corsync 3sec (pad scan at end) Idle 0sec (idle after obs) Setup 20sec (scan setup) ---------- Procedure parameters ------------------------------ PRFLAG YNNN (required procedures) PREOB PREOB (pre-ob procedure) MIDOB MIDOB (mid-ob procedure) POSTOB MIDOB (post-ob procedure) ---------- Timing parameters ------------------------------ Parity 100sec (parity check time) SOURCE 5sec (SOURCE time) Tapetm 1sec (TAPE command time) ---------- General parameters ------------------------------- MODULAR 1sec (start time mark) MINIMUM 0sec (time between obs.)
