FITSH - a software package for astronomical image processing - version 0.9.4
****************************************************************************
This software package provides a set of independent binary programs
(tasks) that 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 (the
related documentation and examples found in this page use the bash
shell). Additionally, some of the processing steps might require minor
or basic operations performed with other tools like awk or text
processing utilities (sort, uniq, paste, ...).
For a brief summary about the individual tasks, check the ``Tasks''
section of the web page of the project, namely at https://fitsh.net/task
Supported systems and requirements
----------------------------------
Actually, the program has been developed under GNU/Linux (Debian, i386
and amd64), and it also tested and seems to work properly on Sun/SunOS,
PC/NetBSD and Mac/OSX systems as well. Cross-compilation is also available
for Windows targets (32-bit and 64-bit systems) but with the lack
of support for dynamic extensions.
However, please note that the primary development platform of the
package is Debian GNU/Linux, thus compilation-time warnings might occur
on other operating systems.
Documentation
-------------
The FITSH tasks have a built-in self-explaining reference documentation
system, that can be asked using the --long-help option. The format of
this long-help output is a standard to the `help2man` utility, with
which nice manual pages can be generated easily (and then these can be
converted to PDF or PostScript as well). See also the `make help2man`
Makefile-target: this target builds the manual pages as well as converts
them into PostScript format if the utilities `help2man` and `groff` are
installed properly on the host operating system.
The web page of the project (https://fitsh.net/) also displays these
manual pages as well as one can find further, completely working
examples.
