1.  NAME

  psmooth1 - Plot smoothed velocities

  2.  SYNOPSIS

  psmooth1(file, psf, year, cruise, note )

  3.  DESCRIPTION

  This function reads the output generated by smoothr, and generates
  plots of the smoothed velocities. It also calculates the filter
  fraction, time gap and distance gap used as parameters in smoothr.
  Hence, this function may be usefull for finding better parameters for
  smoothr.

  4.  PARAMETERS

     file
        Name of input file (output of smoothr).

     psf
        Name of output postscript file.

     year
        Year base used for decimal days in input file.

     cruise
        Name of cruise.

     note
        Additionnal note to print on plot.

  5.  GLOBAL VARIABLES

  The following variables must be defined before calling this function:

     ens_time
        The ensemble time length,in minutes.
