Session Notes for R1 (Rapid Turnaround Monday) session: r1868 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2018.html#r1 for the session purpose. =========================================================== ----- Parameter listing -------------------------------------- Experiment: R1868 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2018-316-17:00:00 End: 2018-317-17:00:00 Current yyyyddd: 2018316 (2018.87) ( 18435 MJD, MON. 12NOV.) Greenwich sidereal time: 20:27:06 (17:00:00 UT) Sun's RA and DEC: 15h 11.3m -17d 48.5 =========================================================== Important Station Information The SEFDs for Ny Alesund were increased to 3000 for both X-band and S-band because the receiver at Ny Alesund is running warm. The X-band was increased by a factor of 3 and S-band by a factor of 2. Matera was tagged along to this schedule file. =========================================================== There is no INT1 session scheduled because it is a holiday at Kokee, Veterans Day. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Ht Ke Ma Ny On Sh Wn Wz Yg 0202+319 18316-170000| 102 126 244 117 127 37 162 244 124| =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ht Ke Ma Ny On Sh Wn Wz Yg 0119+115 18317-165528| 267 94 87 267 111 267 | 0308-611 18317-165548| 31 97 97| 2141+175 18317-165800| 115 115 115 115 | 1104-445 18317-165827| 88 88| =========================================================== SKED Summary from file ./r1868.skd for experiment R1868 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 11.8 Min = 0.0 Max = 144.0 (Baseline On-Sh on 0834-201) RMS = 15.6 Total time: 1440 minutes ( 24.0 hours).
