Session Notes for R1 (Rapid Turnaround Monday) session: r1844 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: R1844 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2018-149-17:00:00 End: 2018-150-17:00:00 Current yyyyddd: 2018149 (2018.41) ( 18268 MJD, TUES 29MAY.) Greenwich sidereal time: 09:28:41 (17:00:00 UT) Sun's RA and DEC: 4h 26.1m 21d 41.1 =========================================================== Important Station Information Katherine was tagged along to this session. Katherine went down for urgent maintenance during May 17 through May 31. Katherine may be operational before May 31. So we were asked to tag Katherine along just in case the station is operational by May 29. =========================================================== There are no observations for Kokee and Wettzell from 18:15 U.T. to 19:45 U.T. Kokee and Wettzell will participate in the intensive session during this period. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Ft Ht Is Ke Kk Ma Ny Kv Ww Wn Wz Yg 0059+581 18149-170000| 96 80 65 21 56 104 104 | 1424-418 18149-170000| 26 20 26 20| 1057-797 18149-170107| 128 128 110| 0955+476 18149-170228| 175 129 187 193 193 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ft Ht Is Ke Kk Ma Ny Kv Ww Wn Wz Yg 1057-797 18150-165152| 195 195 173 154| 1751+288 18150-165239| 125 125 125 | 0307+380 18150-165319| 74 74 | 2008-159 18150-165547| 73 42 248 248 248| 0834-201 18150-165620| 215 215 215 87 | 1330+022 18150-165736| 139 139 139 | 0059+581 18150-165823| 92 92 | =========================================================== SKED Summary from file ./r1844.skd for experiment R1844 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 4.7 Min = 0.0 Max = 84.7 (Baseline Kk-Wn on 0019+058) RMS = 10.5 Total time: 1440 minutes ( 24.0 hours).
