cato - concatinates
RINEX
observation files.
cato [-iseconds] file(s)
DESCRIPTION
cato combines
RINEX
observation, "o", files writing the result to
stdout. In doing this, several tasks are performed:
- the header of the first file is scanned and written,
- the header of subsequent files are scanned and deleted,
- the order of data types in subsequent files is changed to match the
first file,
- optionally, using the -i flag, cato will sample the input data epochs
at the indicated interval, i.e. cato will "decimate" data to a match
the user specified interval. The user specified interval must be in
seconds.
NOTE: cato does minimal error checking and modification. It
will not:
- check that the file are from the same site,
- sort the epochs,
- interpolate the data to new epochs.
EXAMPLES
- Combine two files storing the result in a third.
- cato file1 file2 > file3
- Combine CORS "hourly" files into a "daily" file.
- cato aaaa001[a-x].98o > aaaa0010.98o
- Decimate a file to a 30s data interval.
- mv bbbb0010.98o bbbb0010.98o.save
cato -i30 bbbb0010.98o.save > bbbb0010.98o
