  1.  NAME

  preflyr1 - Plot relative velocities from reference layer

  2.  SYNOPSIS

  preflyr1(file, psf, unit, year, cruise, note )

  3.  DESCRIPTION

  This function reads the output generated by product navigation of
  adcpsect, and generates a plot of the relative reference layer
  velocities.

  4.  PARAMETERS

     file
        Name of input file (output of adcpsect).

     psf
        Name of output postscript file.

     unit

     year
        Year base used for decimal days in input file.

     cruise
        Name of cruise.

     note
        Additionnal note to print on plot.
