Hi SAC users,
Does SAC provide a library function to decimate a time series (similar to
the functionality of the decimate command) that can be used in C/Fortran
codes similar to functions provided to cross-correlate (crscor) and
filter (xapiir) waveforms ? Is there an alternative C library that is as
good as SAC for this ? I think it would involve two steps - an
anti-aliasing filter and then the actual decimation.
Thanks for your help.
Regards,
Avinash
