IVS Analysis Report for VO0244 ($20AUG31VG) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by Sergei Bolotin, NVI, Inc. / NASA Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) Problems: WESTFORD No fringes in y polarization due to bad optical fiber transceiver. Data included and h code threshold set to zero to mitigate effect. Antenna was not tracking from 245-06:06 to 07:18 ut. Missed 48 scans GGAO12M Did not observe due to gearbox replacement. MACGO12M Mark 6 module disk 0 started producing corrupt files at scan 245-1329b, resulting in loss of 7/8, or 12.5% of data for each scan from there through to the end of the experiment. Observed with a warm receiver. RAEGYEB Deleted channels x00lx/y, x01lx/y and x04lx/y due to unstable pcal behavior. Recorded with 10 mhz phase cal tone intervals. Very high SEFD readings reported in the starting message and globally much lower fringe amplitudes and SNRs indicate the receiver was likely warm. The station has a lot of outliers, the rest of observations are much noisier than on other stations. ONSA13NE Band A X and Y pol. fringes are approximately ~50% weaker than other bands. Band B y pol. fringes are ~49% weaker than x pol. As reported by the station. Parameterization comments: None. Other comments: None. ----------------------------------------- Session statistics Observations: 16563 scheduled 10872 correlated (in database) 10793 recoverable (usable) 9647 used Session fit: 24.154 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used GGAO12M 4746 MISSED MISSED 0.0% KOKEE12M 3169 2545 2425 76.5% MACGO12M 4282 3436 3235 75.5% ONSA13NE 4266 2823 2475 58.0% ONSA13SW 4180 2753 2489 59.5% RAEGYEB 3977 3249 2367 59.5% WESTFORD 4441 3361 3115 70.1% WETTZ13S 4065 3419 3188 78.4% --------------- --------- ----------- --------- ------ Station Total** 16563 10793 9647 58.2% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
