Wavelength calibrating the ALPY without a calibration module

In the workshop, Francois ran though wavelength calibrating ALPY spectra using the NeAr lamp in the calibration module. If you don't have this module though it is still possible to get a reasonable calibration using the Balmer lines in the reference star spectrum. (Star Analyser users will be familiar with this technique)  The procedure using ISIS is described in Christian Buil's tutorial here
