  1.  NAME

  preflyr - Plot relative reference layer velocities

  2.  USAGE

  preflyr

  3.  DESCRIPTION

  This Matlab script plots the relative reference layer velocities as
  output from adcpsect together with product navigation.  It is a user
  interface to functions preflyr1(3m) and preflyr2(3m).  It can be
  usefull for looking at the results obtained from different navigation
  sources, or different layers, and select therefore the best solution
  for position fixes.

  4.  PARAMETERS

  The following parameters must be edited:

     file file_1 file_2
        Name of input file(s) (output of adcpsect).  If two different
        datasets are to be compared together,both input files file_1 and
        file_2 should be specified. If only a single dataset is to be
        plotted,the input file may be specified in either file,file_1 or
        file_2.

     str_1 str_2
        Short string that refers to dataset(s) in file_1 and file_2.
        This parameter is ignored when only one dataset is given.

     psfile
        Name of output postscript file.

     new_ps
        If true,the given postscript file will be deleted before
        creating the plots. Else,plots are appended to it.

     velocity_unit
        String specifying the unit used for velocities.

     year_base
        Year base used for decimal days in input file.

     cruise
        Name of cruise.

     note
        Additionnal note to print on plot.
