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 not usable, the station was deselevcted. 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 Observations at the stations are not usable, the station was deselevcted. Parameterization comments: None. Other comments: None. ----------------------------------------- Session statistics Observations: 16209 scheduled 10035 correlated (in database) 4240 recoverable (usable) 3704 used Session fit: 31.704 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used GGAO12M 4003 1947 1767 44.1% ISHIOKA 3815 1472 1046 27.4% KOKEE12M 2207 1206 1076 48.8% MACGO12M 3680 873 815 22.1% ONSA13NE 3620 1295 1172 32.4% ONSA13SW 3689 MISSED MISSED 0.0% RAEGYEB 4035 DESELECTED DESELECTED 0.0% WESTFORD 3504 1687 1532 43.7% WETTZ13S 3865 DESELECTED DESELECTED 0.0% --------------- --------- ----------- --------- ------ Station Total** 16209 4240 3704 22.9% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
