NAME

       mst_print - Printing of MSTrace information.

SYNOPSIS

       #include <libmseed.h>

       void   mst_printtracelist ( MSTraceGroup *mstg, flag timeformat,
                                   flag details, flag gaps );

       void   mst_printsynclist ( MSTraceGroup *mstg, char *dccid,
                                  flag subsecond );

       void   mst_printgaplist ( MSTraceGroup *mstg, flag timeformat,
                                 double *mingap, double *maxgap );

DESCRIPTION

       mst_printtracelist  prints  a  formatted  list  of  the  MSTrace  segments  in  the  given
       MSTraceGroup.  If the details flag is greater than 0 the sample rate and sample count  are
       printed  for  each  trace.   If  the  gaps flag is greater than zero the time gap from the
       previous MSTrace (if the source name matches) is printed.  All  output  is  printed  using
       ms_log(3) at level 0.

       mst_printsynclist   prints  a  formatted  list  of  the  MSTrace  segments  in  the  given
       MSTraceGroup similar to mst_printtracelist but the format is a SYNC listing.  If  a  dccid
       string  is  supplied it will be used along with the current system date to create the SYNC
       header line.  If the subsecond flag is true (non-zero) the time values in the  SYNC  lines
       will  include  full  libmseed precision, otherwise they will be truncted to integer second
       values.

       mst_printgaplist prints a formatted list of the gaps between MSTrace segments in the given
       MSTraceGroup.   If  mingap  or  maxgap  is not NULL their values will be enforced and only
       gaps/overlaps matching their implied criteria will be printed.

       The timeformat argument for both  mst_printtracelist  and  mst_printgaplist  controls  the
       format of the resulting time strings.  Possible formats are:

       0 : SEED time format (2005,146,00:00:00.000000)
       1 : ISO time format (2005-05-26T00:00:00.000000)
       2 : Epoch time, seconds since the epoch (1117065600.00000000)

       Both  mst_printtracelist  and  mst_printgaplist  represent time overlaps as negative gaps.
       For a single sample overlap the value of the gap is  calculated  as  zero,  this  will  be
       printed as "-0" or negative zero to indicate an overlap.

GAP/OVERLAP RULES

       The  existence  of  gaps and overlaps is implicit in the structure of the MSTraceGroup, no
       special processing is done to detect gaps and overlaps in these routines.

       The value of a gap is calculated as the difference between the time  of  the  last  sample
       before  the gap and the time of the first sample after the gap.  No sample 'coverage' time
       is included.

       The value of an overlap is calculated as the time between two samples which represent  the
       maximum amount of timeseries overlap.

       When  the  MSTraces  in  the  MSTraceGroup  include  a  small  segment  that is completely
       overlapped by another larger segment the gap/overlap value will not be correct for  either
       the smaller segment or the segment following it.
