fgmav  --  compute averages of high-resolution CLUSTER FGM data

USAGE:

 ... | fgmav { {-f|-s|-m} [<int>] | -p [<flt>] | -t <tlfile> } | ...

 The program reads high-resolution CLUSTER FGM data (in fgmtvec_t format)
 from stdin, computes averages and variance, and writes them to stdout.

 In the FGM status and id word, the flag for averaged data is set, and
 the quality of averaging is indicated by a bit field representing the
 number of missing data points.

OPTIONS:

  -f <int>    compute averages over 1/<int> seconds.  Every <int>th
              averaging interval starts at full UT second.
              <int> must be smaller then the sampling frequency.

  -s <int>    compute averages over <int> seconds.  Averaging intervals
              begin at a UT of <int>, 2*<int>, 3*<int>, ... seconds.

  -m <int>    compute averages over <int> minutes.  Averaging intervals
              begin at a UT of <int>, 2*<int>, 3*<int>, ... minutes.

     <int>    integer number specifying the length of an averaging
              interval in minutes, seconds, or as fraction of a second.
              Default is 1.

  -p <flt>    compute averages over one spin rotation.  Averaging inter-
              vals begin at a spin phase of <flt> degrees.

     <flt>    float number specifying the offset spin angle (in degrees)
              at which a spin averaging interval starts.  Default is 0.

  -t <tlfile> read start, end, and tag of each averaging interval from the
              timelist file <tlfile>.  This is a binary file in the timelist
              format specified by UK CDHF.

  -V          print version number on stdout, then exit.
