vgeo_grd(3m)

NAME
vgeo_grd - Plot geostrophic current

SYNOPSIS
vgeo_grd(year_base, file_name, x, grd, filter, title, institute, info )

DESCRIPTION
This function is called by vgeo(1m) for plotting geostrophic current at the specified depths (all of them if no depths are specified). Velocities are first averaged together to remove large variations, and lowpass filtered to remove high frequency oscillations. It takes as input file a grd file as those generated by vgeo(1). This file has the following columns: time (decimal day) longitude latitude depth geostrophic current

PARAMETERS

year_base
    Year base used in vgeo(1).

file_name
    Root name of data file. The function will automatically add the suffix .grd to it.

x   Index to x-variable. This is a number corresponding to the x column in the data files. Possible values are: time longitude latitude If negative,the axis direction will be reversed.

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

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

title
    Title of plot.

institute
    Institute stamp.

info
    String with additionnal information on plot.

OUTPUT
The generated plot is saved in file file_name_grd.ps.
