NAME

       msr_samprate - Determine sample rate from an MSRecord structure

SYNOPSIS

       #include <libmseed.h>

       double  msr_samprate ( MSRecord *msr );

       double  msr_nomsamprate ( MSRecord *msr );

DESCRIPTION

       msr_samprate will calculate a double precision sample rate in samples per second using the
       header values in the specified MSRecord.  If a Blockette  100  is  included,  the  "Actual
       sample  rate"  (field  3)  will  be  returned,  otherwise  a  nominal  sample rate will be
       calculated from the sample rate factor and multiplier in the fixed section data header.

       NOTE:  The  sample  rate   for   a   MSRecord   structure   is   available   directly   at
       MSRecord.samplerate.   libmseed  based  programs  should  use  that  sample  rate whenever
       possible (msr_unpack uses msr_samprate to set MSRecord.samplerate).

       msr_nomsamprate will calculate a double precision sample rate in samples per second  using
       the sample rate factor and multiplier in the fixed section data header.

RETURN VALUES

       msr_samprate returns a double precision sample rate on success and -1.0 on error.

       msr_nomsamprate returns a double precision sample rate on success and -1.0 on error.
