NAME

     logsmooth  - module to do simple  median  filtering  on  log
     data

SYNOPSIS

     logsmooth [ -lmed ] [ -mnpass ] [ -V ] [ -? ] <inlog >outlog

DESCRIPTION

     logsmooth reads in a log from standard input, smooths  using
     two  types  of  median  filtering, and writes the results to
     standard output.  Each line of the log must be in  the  form
     of  depth  (or layer thickness), velocity (or slowness), and
     density.  The filters are applied to both the  velocity  and
     the density.

     logsmooth gets both its input from stdin ( < ), its output (
     >  )  goes  to  stdout,  and its parameters from the command
     line.

  Command line arguments
     -l ist
          Enter the length in points of the type 2 median filter.
          This filter is a standard median filter and can be many
          points long.  Whether this is used or  not  (default  =
          none)  there  is  a  type 1 median filter which will be
          applied regardless.  This is a  very  sophisticated  3-
          point  smoother  designed  to mildly condition the log,
          i.e. get rid of glitches

     -m npass
          Enter the number of passes to make using  the  standard
          median filter (default = 1)

     -V   Enter the command line argument '-V' to get  additional
          printout.

     -?   Enter the command line  argument  '-?'  to  get  online
          help.   The program terminates after the help screen is
          printed.
