  ctdprf - Plots CTD profiles

  2.  SYNOPSIS

  ctdprf(year_base, prf_file, pos_file, plot_title, plot_prf, note )

  3.  DESCRIPTION

  This Matlab function makes a plot of CTD profiles.  Input file can be
  generated with xtract(1). CTD input file must have the following
  columns:

  1. Pressure (db)

  2. Potential Temperature (deg C)

  3. Salinity (ppm)

     Position input file must have the following columns:

  1. Time in decimal days

  2. Longitude in degrees

  3. Latitude in degrees

  4.  PARAMETERS

     year_base
        Base year used in input position file.

     prf_file
        Input CTD data file.

     pos_file
        Input position file.

     plot_title
        Title for plot.

     plot_prf
        A string with profile decriptors to plot. These may be the
        following characters: T (temperature),S (salinity) and s
        (sigma).

     note
        Additionnal string to plot at lower left corner of plot
