eop_from_sinex file1 {file2 ...}or as a filter:
cat file | eop_from_sinexAny polar motion values are rescaled, reformated and printed to stdout.
The default format is that used by the IGS, but the -n flag forces the output to mimic the older NOAA format.
eop_from_sinex is an ANSI standard C program. All source code is available from the author.
