Hello everybody,

me and my "amateur astronomers" friends are working on a sample of emission-line stars taken by the Kohoutek catalog (III/205 in the Vizier database at CDS-Strasbourg http://cds.u-strasbg.fr/     H-alpha Stars in Northern Milky Way  Kohoutek+ 1997). We use IRAF as general standard reduction package and, since the Kohoutek stars are generally on the galactic plane, we focused on the  usage of the DAOPHOT package for measuring magnitudes in crowded fields with the tecnique of the aperture correction. We wrote some kind of a tutorial and a few little programs in Python and Scilab useful for the reduction processes.   If anybody is interested in our work we will greatly appreciate any comments and suggestion from the AAVSO community.  Here is the link to a Dropbox public folder address of the tutorial for download:

In the Appendix you will find other links for downloading the Python and Scilab programs we wrote.
