Notes for running idl program snz

Installation
----------------

1.  In a directory which is included in your IDL path, Un-tar the file snz.tar 
    e.g. unix>  tar -xvf snz.tar

2.  Edit snz_setup.pro so that 'sndir' is set to the directory where you
    are setting things up


Running
-------

Start IDL. Then run the setup file (only need to do this once per IDL
session)

IDL> @snz_setup

Then the following gives you an example [where test.dat is
as ascii file of 2 columns, wavelength and flux].

IDL> snz, datafile='test.dat'

You will then have a menu from which to choose various options
including printing.
