Dear colleagues,
Following some requests, the content of the
weekly SINEX combination summary reports is now available in
a more "user/computer" friendly format.
The content of the weekly SINEX Combination was reformatted.
All the weekly SINEX Combination reports that were originally sent
to CDDIS have been included, going back to GPS week 0999 (99/02/28),
when the first combination of the "pilot phase" was submitted.
The pilot phase was included for completeness. The tables/graphics
will be updated when weekly combinations become available.
Some processing (e.g.: transformations) may be included later on.
Note that the combinations were not official until GPS week 1050
(00/02/20). Some plots (*.ps, *.jpg) were also included for
convenience. Those will be included in WEB pages being prepared
by M. Bourassa and will be available shortly.
The reformatted files can be found in:
ftp macs.geod.nrcan.gc.ca
cd /pub/requests/sinex/sum
The table files name & contents is divided by section #:
Section Contents
======= ========
5-1 Variance Factor
5-2-1 Station coordinates residuals statistics w.r.t.
reference frame
5-2-2 Station coordinates residuals statistics w.r.t.
IGS weekly combination
5-2-3 Station coordinates residuals statistics w.r.t.
IGS cumulative combination
5-3-1 Estimated transformation parameters from each solution
to the epoch IGS realization of ITRF.
5-3-2 Estimated transformation parameters sigmas from each
solution to the epoch IGS realization of ITRF.
5-4 Apparent Geocenter estimate and formal std.
5-5-1 Earth Rotation Parameters (ERP) weighted average
residuals w.r.t. the IGS weekly combination.
5-5-2 Earth Rotation Parameters (ERP) residuals std.
w.r.t. the IGS weekly combination.
and by solution name (when appropriate):
cod emr esa gfz jpl ngs sio mit ncl igs.
The following naming convention is used for the generated table files:
Sect_Soln.sum
Where:
Sect = Section/subsection #
Soln = AC & GNAAC etc solution name.
The columns in the files are identified along fith the units
(when applicable).
For example, an extract of the table file for section 5-1 and solution
"cod" is:

The tabular information is also available in graphical form.
The graphics are available in postscript (*.ps) and the "jpg" formats.
They are grouped by section# and by column *.
Within each section, a plots is available for the time series for each
column.
The following naming convention is used for the generated graphics files:
Sect_Coln.sum
Where:
Sect = Section/subsection # (See above)
Coln = column name as identified below.
For each section in the "Coln" extension for the plotted column
