Session Notes for R1 (Rapid Turnaround Monday) session: r1999 Prepared by C. Thomas, NVI, Inc./GSFC Refer to http://ivscc.gsfc.nasa.gov/program/descrip2021.html#r1 for the session purpose. =========================================================== ----- Parameter listing -------------------------------------- Experiment: R1999 Description IVS-R1 Scheduler: NASA Correlator: BONN Start: 2021-138-17:00:00 End: 2021-139-17:00:00 Current yyyyddd: 2021138 (2021.38) ( 19353 MJD, TUES 18MAY.) Greenwich sidereal time: 08:46:24 (17:00:00 UT) Sun's RA and DEC: 3h 42.9m 19d 42.4 =========================================================== Important Station Information Ny Alesund-South was tagged along to this schedule file. The SEFDs for Ny Alesund were increased to 3000 for both X and S band to compensate for their warm receiver. =========================================================== 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 Ht Ho Is Kk Nt Ny Ns On Sh Ww Wz Ys 0727-115 21138-170000| 40 20 51 40 66 66| 2214+241 21138-170000| 86 58 86 47 | 0308-611 21138-170119| 200 200 157 200 | 3C418 21138-170208| 70 48 56 70 57 20 70 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ag Ht Ho Is Kk Nt Ny Ns On Sh Ww Wz Ys 0805+410 21139-165436| 88 158 119 158 99| 1144-379 21139-165510| 131 127 99 131 | 2052-474 21139-165544| 23 23 | 3C371 21139-165754| 121 121 121 121| 1213-172 21139-165815| 100 100 100 100 100 100 | =========================================================== SKED Summary from file ./r1999.skd for experiment R1999 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 10.9 Min = 0.0 Max = 96.0 (Baseline Sh-Ys on 2126-158) RMS = 13.2 Total time: 1440 minutes ( 24.0 hours).
