IVS Analysis Report for VO1245 ($21SEP02VG) 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: KOKEE12M Fmout.py couldn't process the K2 logfile. All lines up to '2021.245.17:19:47.04.schedule=vo1245k2,#1' had to be deleted. ONSA13NE Station reports: DBBC3 IFD (VGOS band B polarisation V) has significant loss of signal in correlated data, plus extra spikes every 1.7 mhz in the pcal autocorr spectra. This problem has likely been present in all oe data since 2019. The problem is finally under investigation and may be hardware problem. Vdif payload size has been changed from 8192 bytes to 8000 bytes. For multi-file (datastream) correlation, this means using a total vdif packet size of 8032 bytes instead of 8224 as it was before. Notch filtering not optimal. ONSA13SW Vdif payload size has been changed from 8192 bytes to 8000 bytes. For multi-file (datastream) correlation, this means using a total vdif packet size of 8032 bytes instead of 8224 as it was before. Notch filtering not optimal. The staion residuals have a bimodal pattern with an offset ~300ps, ~30% of observations were deselected. WESTFORD Not tracking (22:35-23:45) WETTZ13S Module was too small (32 tb), hence not all data could be recorded. Missed ~2hrs of the session. Parameterization comments: None. Other comments: This is a second submission due to refringing including 'mbd_anchor sbd' in control file. Correlation done with DiFX-2.5.4 with multi-files for stations Oe and Ow. Post-processing done with HOPS version 3.23. ----------------------------------------- Session statistics Observations: 20509 scheduled 19665 correlated (in database) 18392 recoverable (usable) 16096 used Session fit: 21.433 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used GGAO12M 6123 5920 5385 87.9% KOKEE12M 5074 4888 4360 85.9% MACGO12M 6089 5888 5228 85.9% ONSA13NE 5971 4588 4239 71.0% ONSA13SW 5953 4816 3295 55.4% WESTFORD 6114 5647 5165 84.5% WETTZ13S 5694 5037 4520 79.4% --------------- --------- ----------- --------- ------ Station Total** 20509 18392 16096 78.5% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
