Introduction

What is fitsh
fitsh is:
This software package provides independent binary programs (so called tasks) which performs various steps of astronomical image reduction and data processing. These tasks are designed for execution from a UNIX command line shell or shell script. Each of these tasks performs a specific operation (e.g. transforming an image to another reference frame, search and identifiy stars or other point-like sources, do photometry, transform/display a FITS image to a popular graphics format, …) while the details of a certain operation are specified via command switches and arguments. Therefore this package does not need any higher level operating environment than a standard UNIX shell, however, processing the related data might require a little more knowledge of the used shell itself. If you find this program useful in your research, please cite 2012MNRAS.421.1825P as “2012, MNRAS, 421, 1825”. See also the web page of the project, found at http://fitsh.net/.
