Session Notes for R1 (Rapid Turnaround Monday) session: r1938 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2020.html#r1 for the session purpose. =========================================================== ----- Parameter listing -------------------------------------- Experiment: R1938 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2020-076-17:00:00 End: 2020-077-17:00:00 Current yyyyddd: 2020076 (2020.21) ( 18925 MJD, MON. 16MAR.) Greenwich sidereal time: 04:38:58 (17:00:00 UT) Sun's RA and DEC: 23h 47.4m -1d 21.8 =========================================================== Important Station Information Ny Alesund - South was tagged along to this schedule file. Also Ny Alesund - South is observing with a warm receiver. So the SEFDs for Ny Alesund - South were increased to 4410 for X-band and 3900 for S-band. =========================================================== 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 Ag Bd Ft Ht Is Kk Ma Ny Ns Kv Sv Ww Wz Zc 0202+319 20076-170000| 290 290 167 116 290 48 88 48| 1149-084 20076-170000| 20 32 40 97 97 | 1243-160 20076-170225| 20 23 60 60 | 2113+293 20076-170255| 20 20 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ag Bd Ft Ht Is Kk Ma Ny Ns Kv Sv Ww Wz Zc OJ287 20077-164112| 20 20 22 20 20 22 20 20 20| 1741-038 20077-164249| 20 20 26 26 | 0745+241 20077-164255| 42 103 103 21 55 31| 1255-316 20077-164412| 23 23 | 0656+082 20077-164514| 35 35 20 | 1144-379 20077-164524| 69 202 202 | 2037-253 20077-164533| 409 409 | 0537-286 20077-164611| 423 203 423 269 118| 0017+200 20077-164823| 20 20 | 1243-160 20077-164939| 20 23 60 60 | 1324+224 20077-165118| 106 96 106 | 0847-120 20077-165156| 29 64 68 32 68 32| 1954-388 20077-165353| 41 41 | 0648-165 20077-165414| 20 20 20 20| 0104-408 20077-165450| 174 174 60 | 1149-084 20077-165526| 20 40 97 97 | 0446+112 20077-165619| 34 34 20 21 20| 1639-062 20077-165642| 22 22 | 1057-797 20077-165820| 41 41 | 0202+319 20077-165831| 20 20 20 20 20| =========================================================== SKED Summary from file ./r1938.skd for experiment R1938 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 6.5 Min = 0.0 Max = 125.2 (Baseline Ft-Ny on 1741-038) RMS = 10.0 Total time: 1439 minutes ( 24.0 hours).
