IVS Analysis Report for VO2118 ($22APR28VG) 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: ISHIOKA Scans have a shorter recording time due to data write failure (Band-A: 118-23:49--119-17:59). Most scans are missing band A data. Numerous errors when generating proxy cable cal due to missing channel data in scans. MACGO12M Mechanical problems (119-1018 -- 119-1759). Missed few scans ONSA13SW Did not participate. WESTFORD Control room switch problem (118-18:00--118-20:02). WETTZ13S No detections in bands B or C. Bands A and D do not combine properly in psuedo-Stokes I fringes even after making sampler delay adjustments. Since they could not be calculated, inter-channel and Y-X offsets were taken from VO2097. Observations at the stations are hardly usable. RAEGYEB Sources not reached (119-17:41-119-18:00). Fourphase found a bimodal. distribution for Y-X offsets. Values were chosen from one of the distributions. Parameterization comments: None. Other comments: This is a second submission of the database. The correaltor tried to revive WETTZ13S and RAEGYEB. RAEGYEB is almost ok, but WETTZ13S still has many problems. The both stations this time are included in the solution. ----------------------------------------- Session statistics Observations: 16209 scheduled 9967 correlated (in database) 8414 recoverable (usable) 6097 used Session fit: 35.065 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used GGAO12M 4003 2951 2415 60.3% ISHIOKA 3815 2200 1351 35.4% KOKEE12M 2207 1447 1210 54.8% MACGO12M 3680 1110 981 26.7% ONSA13NE 3620 2480 1846 51.0% ONSA13SW 3689 MISSED MISSED 0.0% RAEGYEB 4035 2180 1852 45.9% WESTFORD 3504 2432 1980 56.5% WETTZ13S 3865 2028 559 14.5% --------------- --------- ----------- --------- ------ Station Total** 16209 8414 6097 37.6% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
