These pages describe the OSU photometric reduction pipeline and related software packages written and maintained by Ohio State for use with microlensing followup observing and data reduction. This site should be considered the definitive source for the "official" versions of all such software. If you get copies from somebody else, you do so at your peril.

These documents are really only of local (OSU) interest, as they give instructions on how to run various local OSU daily reduction tasks (like running our local version of the photometry pipeline, etc.).

These programs are provided for the observing and analysis software written and distributed by Ohio State. All code here is public domain, unless otherwise specified. Most of the software was designed for the OSU Photometry Reduction Pipeline used when we were part of the PLANET collaboration. The basic software is an adaptation of the PLANET reduction pipeline. While it creates basic PLANET-conformal binary archive files, we have our own control scripts and modified reduction steps that make it run quieter (and faster) than the stock PLANET software.

CFITSIO Libraries

All of the programs that handle FITS format data files use the cfitsio libraries written by Bill Pence and distributed by HEASARC at the NASA Goddard Space Flight Center. We do not distribute cfitsio ourselves, but it can be readily obtained from the FITSIO webpage at HEASARC:

http://heasarc.gsfc.nasa.gov/docs/software/fitsio/

Full documentation is also available on the FITSIO webpage.

Notice about CFITSIO

The latest version of CFITSIO is v3.060 (released 2007 Aug 27). We have tested ccdproc, autolog, and fwhmsky (part of the pipeline package) with CFITSIO v3 and later on various Linux systems (RedHat 7.x, FC3-5, and CentOS5).
