1. Introduction
1.1. Knowledge Required
With all the help from major Linux distributions such as SuSE, Redhat,
Caldera and many others, Linux based systems are becoming easier to
use. However, there is still some need of understanding of basic UNIX
skills to make the most of Linux. Thus, this HOWTO will assume that
the reader has at least a basic knowledge of using a UNIX system
including the ability to compile and install programs. A few
resources we have found useful over the years include:
� "A Practical Guide to the UNIX System", Mark G. Sobel
� "Advanced Programming in the UNIX Environment", the late W. Richard
Stevens
� "Running LINUX", Matt Welsh et al.
� "LINUX Device Drivers", Alessandro Rubini
Similarly, this is not a tutorial or reference for astronomy
principles or astronomical instrumentation. Astronomy is perhaps the
grandest of all sciences, employing widely disparate disciplines in a
bold attempt to understand nothing less than the universe itself. Your
interests will lead in many directions. A few references we have used
include:
� "Astronomy with your Personal Computer", Peter Duffett-Smith
� "Astronomy on the Personal Computer", Oliver Montenbruck et al
� "Textbook on Spherical Astronomy", W. M. Smart
� "The Astronomy and Astrophysics Encyclopedia", Stephen P. Maran,
ed.
1.2. Scope
The authors define the scope of this HOWTO as primarily an index to
Linux tools applicable in some fashion to the pursuit of Astronomy. It
is NOT our intention to list WWW astronomy references in general. Our
own interests tend more towards the technology than the pure science
and so we welcome contributions from others who have found Linux tools
which contribute in other ways to Astronomy. Please contact us at the
address above.

2. Software
2.1. Collections
Here are some links to collections and other indexes of Linux
astronomy software.
� The Linux for Astronomy CDROM
� Scientific Applications on Linux (SAL), Physics and Astronomy
� Linux Applications and Utilities Page, Science and Math
� AstroMake is a utility intended to make installations of some
common astronomical packages (in binary form) easy.
� The linuxastro mailing list also contains a list of applications
and packages. For more information, see linuxastro.
2.2. Planetarium Programs
Here is discussion of whole programs for use in finding objects,
natural and man-made, in the sky which run on Linux.
� XEphem has been the pet project of one of us (Downey) for the past
15-odd years. It has grown to become one of the more capable
interactive tools for the computation of astronomical ephemerides.
� XSky is by Terry R. Friedrichsen,
[email protected]. XSky is
essentially an interactive sky atlas.
� Skymap is an astronomical mapping program written in Fortran and C
for unix workstations by Doug Mink of the Smithsonian Astrophysical
Observatory Telescope Data Center.
� Xplns reproduces real starry sky on your display of X Window
System.
� AstrHorloge is a small astronomy software that shows a sky map,
give you the coordinates of stars and planets.
� Nightfall is an astronomy application for fun, education, and
science. It can produce animated views of eclipsing binary stars,
calculate synthetic lightcurves and radial velocity curves, and
eventually determine the best-fit model for a given set of
observational data of an eclipsing binary star system.
2.3. Libraries
This section discusses bits and pieces of software that can be used to
form the basis for specialized projects.
� SLALIB, part of the Starlink Project, is a complete library of
subroutines for astrometric computations.
� Astrophysics Source Code Library is a collection of links to
numerical astrophysical process models.
� Astronomy and numerical software source codes is a collection of C
codes related to astronomy.
� How to compute planetary positions.
2.4. Other
Every list needs a miscellaneous section, and this is it for Software.
� IRAF is a gigantic but exceptionally capable astronomical analysis
system, shepherded over the past 20-odd years by Doug Tody of NOAO.
It has accumulated innumerable authoritative contributions from
leading astronomers in all areas of astronomical data analysis. If
you have a serious interest in astronomical data reduction and
significant time to invest, this system will reward you mightily.

3. Astronomical Images over the web
Much effort exists to allow access to Astronomical image file type
such as FITS from any web browser. Here are some pointers.
3.1. List
The folks at harvard have a list of Image Servers and Image Browsers.
� Astronomical Images Over the Web
4. Organizations
� The yearly Astronomical Data Analysis Software and Systems, ADAAS,
Conference Series provides a forum for scientists and computer
specialists concerned with algorithms, software and operating
systems in the acquisition, reduction and analysis of astronomical
data. The program includes invited talks, contributed papers and
poster sessions as well as user group meetings and special interest
meetings ("BOFs''). All these activities aim to encourage
communication between software specialists and users, and also to
stimulate further development of astronomical software and systems.
� The linuxastro mailing list,
[email protected], is
for people who are interested in porting astronomical software to
linux. For more information, see linuxastro.
5. Hardware Control
More folks are using Linux to control equipment. Users range from
amateur astronomers in the field to professional observatories.
5.1. Telescope Control
� OCAAS is a complete Observatory Control and Astronomical Analysis
System for Linux.
� XEphem has the capability to communicate with a telescope control
daemon process.
5.2. CCD Camera Control
� Apogee Instruments Inc supports their line of professional CCD
cameras under Linux.
� SBIG offers some assistance with operating their ST7 and ST8 CCD
cameras under Linux.
6. Installation Help
You need to know what you're doing with Linux and installing programs,
but help is available for some programs. Here are some ways to make
life easier.
� AstroMake is is a utility intended to make installations of some
common astronomical packages (in binary form) easy.
� XEphem requires several elements to exist on your machine. Life is
much simpler with the CDROM version of the program as it contains
an installation script which loads the appropriate precompiled
binary for most systems and places all auxiliary files to the
correct spots. See XEphem CDROM
