Wettzell will participate in the intensive session during this two hour period. Wettzell was tagged along to this schedule file because work will be done on Wettzell's ACU this week. Ny Alesund was NOT tagged along to this schedule file. Tigo's number of observations increased slightly with Ny Alesund being scheduled as a regular station. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Gc Ny On Tc Ts Wz 0607-157 05129-170000| 105 105 40| 1547+507 05129-170000| 113 113 96 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Gc Ny On Tc Ts Wz 0607-157 05130-164010| 108 108 40| 1923+210 05130-164039| 40 40 40 | OK290 05130-164316| 79 79 60| OQ208 05130-164342| 40 40 | 0743+259 05130-164540| 109 109 98| 1741-038 05130-164545| 40 40 | 1821+107 05130-164710| 49 49 | 1351-018 05130-164908| 47 47 | =========================================================== SKED Summary from file ./r1174.skd for experiment R1174 (all scans with at least one subnet station) Average number of obs. per baseline per source (normalized by up-time) = 9.8 Min = .0 Max = 70.8 (Baseline Gc-Tc on 1237-101) RMS = 11.5 Total time: 1430 minutes ( 23.8 hours).
