Astronomical Photometry CD

Authors: Arne A. Henden & Ronald H. Kaitchuck For the Adanced Amateur & Professional Astronomer (Software for the IBM-PC)In addition to writing a book on the subject Astronomical Photometry, the authors have written a professional level computer program based upon the techniques described in their book. The software package is a fairly complete photoelectric photometry data reduction system. There are several programs, each of which handle a different aspect of the reduction process. This modularity allows the user the flexibility to adapt the reduction process to their specific needs. Specifics are: Input and output to the programs is via simple ASCII files. There are five major programs which calculate: dead time (if required) instrumental magnitudes and colors air mass heliocentric Julian dates extinction coefficients transformation coefficients to the Johnson system conversion to the standard photometric system the reduction of differential photometry Data from eith
