SPEFO is a small, yet powerful program used for processing stellar spectra at the Astronomical Institute of the Academy of Sciences of the Czech Republic in Ondrejov. It was originally written in 1990 by Dr. Jirí Horn for processing spectral plates obtained with the 2m telescope of the Ondrejov observatory and scanned with the local five channel microphotometer. Since then the code had been under constant improvement until the sudden death of the author in December 1994. Currently SPEFO is used mainly for the reduction of data from the Ondrejov Reticon detector (1872 pixels, 12 bit A/D), however it can process data from other instruments too, provided that they are in FITS one-dimensional format.
