1.  NAME

  vgeo - Plot geostrophic current and reference levels

  2.  USAGE

  vgeo

  3.  DESCRIPTION

  This Matlab scripts is an interface to functions vgeo_grd(3m) and
  vgeo_sta(3m). It is used to plot geostrophic current generated by
  vgeo(1), as well as statistics about the reference level.

  4.  PARAMETERS

  The following parameters must be edited:

     year_base
        Year base used in vgeo(1).

     file_name
        Root name of data file. Functions called within this script will
        add automatically the suffixes to get name of grid and
        statistics files.

     x_var
        Index to x-variable. This is a number corresponding to the x
        column in the data files. Possible values are:

        1. time

        2. longitude

        3. latitude

        If negative,the axis direction will be reversed.

     n_filter
        Number (larger than one) used to filter data. Set it to one to
        disable filtering.

     depth
        Vector containing list of depth from which grd data should be
        plotted.  If empty,all available depths are plotted.

     plot_title
        Title of plot.

     institute
        Institute stamp.

     info
        String with additionnal information on plot.

     plot_grd
        If true,plotting of geostrophic ccurrent at the specified grid
        points is enabled.

     plot_sta
        If true,plotting of statistics about the reference level is
        enabled.
