IVS Analysis Report for AOV020 ($18FEB27XA) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by David Gordon, NASA Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) This is a remake of the AOV020 session with data from SYOWA added in. Problems: Source 1600+43B was renamed to 1600+43A at GSFC. During the course of generating ICRF3, it was found that observations of these two sources yielded the same positions, so all occurances of 1600+43B were changed to 1600+43A. This is a weak source and it was not detected in this session. HOBART26: No usable data. Receiver was in the focus cabin instead of at the focal point. KOGANEI: Missed 313 scans from 059-0503 to 059-1725 due to operator misunderstanding. WARK12M: Missed 151 scans from 058-1730 to 059-1134 due to staff scheduling issue. Difficult ambiguity resolution because the single-band delays are not usable. Parameterization comments: None. Other comments: Currently there are some problems in generating EOP and Sinex solutions with this database as well as with the AOV024/18JUN19XA session. We are investigating and will not submit the databases until the problems are resolved. ----------------------------------------- Session Statistics Observations: 2534 scheduled 1352 correlated (in database) 919 recoverable (usable) 880 used Session fit: 77.298 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HOBART26 766 MISSED MISSED 0.0% ISHIOKA 811 430 417 51.4% KASHIM11 570 322 309 54.2% KATH12M 708 365 354 50.0% KOGANEI 640 115 96 15.0% SYOWA 305 162 159 52.1% WARK12M 617 101 95 15.4% YARRA12M 651 343 330 50.7% --------------- --------- ----------- --------- ------ Station Total** 2534 919 880 34.7% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
