Welcome to the FITSH Wiki pages. Here you can find a detailed description and a series of examples related to the various tasks of the FITSH package. Please note that both the reference manuals of the package tasks and the official download section are accessible from the main http://fitsh.net/ webpage.
The current stable version of FITSH is 0.9.2.
By installing from source, FITSH follows the standard ./configure && make && make install procedure. See this page for further details. FITSH can also be compiled as a Debian package and can be installed system-wide using a Debian-based package manager (dpkg, apt-get, ...).
This page describes you how can one begin to have experiences with FITSH. Basically, first install FITSH itself (and some additional packages which might also be useful in the future) then the tasks are readily be availble for image processing!
