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: Correlation done with DiFX-2.5.4 with multi-files for stations Oe and Ow.
Post-processing done with HOPS version 3.23.

NO DATA: The baseline's stations were both correlated,
but they did not observe together.
DESELECTED: Usable data was generated for the baseline,
but the analyst rejected it.
