prefabs(1m)

NAME
prefabs - Plot absolute reference layer velocities

USAGE
prefabs

DESCRIPTION
This Matlab script plots the absolute reference layer velocities as output from refabs. It is a user interface to functions prefabs1(3m) and prefabs2(3m). It can be usefull for looking at the results obtained from different navigation sources, or different layers, and select the best solution for position fixes.

PARAMETERS
The following parameters must be edited:

file file_1 file_2
    Name of input file(s) (output of refabs). 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.

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.
