prefabs2(3m)

NAME
prefabs2 - Compare absolute velocities from reference layer

SYNOPSIS
prefabs2(file1, fstr1, file2, fstr2, psf, year, cruise, note )

DESCRIPTION
This function reads two output files generated by refabs, and compares the absolute reference layer velocities of both input datasets. This can be usefull when looking for the best reference layer used for corecting position fixes.

PARAMETERS

file1
    Name of first input file (output of refabs).

fstr1
    Short string that refers to dataset in file1.

file2
    Name of second input file (output of refabs).

fstr2
    Short string that refers to dataset in file2.

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.

GLOBAL VARIABLES
Although they ar not used by this function, the following variables should be defined before calling it:

min_speed
    Minimum allowed speed,in m/s. This should be the same value that will be used later in smoothr.

max_speed
    Maximum allowed speed,in m/s. This should be the same value that will be used later in smoothr.

ens_time
    The ensemble time length,in minutes.
