WYFFOS/AUTOFIB2 on the WHT

Reduction Software

Jim Lewis at RGO has written an IRAF data reduction task, Wyf_red, specialized for the extraction of the multi-fibre spectra generated by WYFFOS. This is an IRAF script task which is based on the generalised fibre reduction task `dofibres' which was written by Frank Valdes at NOAO. This software attempts to automate the data reduction as much as possible, and will do bias subtraction, aperture defining, arc extraction and scrunching, correction for relative fibre throughput using offset sky frames or flatfields, sky subtraction, and finally object extraction, with a minimum of user input. The tar file containing the iraf scripts, the user manual and installation guide are all available via anonymous ftp. Note that the tar file contains all the iraf scripts in the 'rgo' package, of which the wyf_red routine is only a part.
