Plot raw and smoothed velocities

## 1. SYNOPSIS

crfp2(year, psfile, ax, RefMatName, SmMatName, min_speed, max_speed, max_gap_ratio, cruise, note )

## 2. DESCRIPTION

This is a modified version of Matlab function callrefp which uses more parameters. It is used to plot raw and smoothed position fixes. It can be called from Matlab script crfp(1m). Parameters min_speed, max_speed and max_gap_ratio should have the same value as those used in smoothr.

This implementation will also calculates the velocity uncertainty between raw and smoothed velocities, giving an idea of smoothing effects, and therefore data quality.

## 3. PARAMETERS

year

  Base year used in input files.

psfile

  Name for output postscript file.

ax

  Vector with start time,time intervall,start velocity and velocity intervall for plot axes.

RefMatName

  Name of output mat file from refabs (parsed through ref2mat).

SmMatName

  Name of output mat file from smoothr (parsed through sm2mat).

min_speed

  Minimal allowed ship speed for processing good fixes.

max_speed

  Maximal allowed ship speed for processing good fixes.

max_gap_ratio

  The maximal gap ratio allowed for processing good fixes.

cruise

  String to insert in the title.

note

  Additionnal string to print on plot.
