Astronomical Software

IRAF

IRAF is a heterogeneous collection of routines and packages for all sorts of tasks, but it is first of all a data reduction environment, for which their is extensive on-line documentation.

PYRAF

PyRAF is a new command language for IRAF based on the Python scripting language. It is useful both for interactive data analysis and for writing analysis scripts. PyRAF coexists with the current IRAF CL. We currently have version v1.2.1 installed, which includes a number new PyRAF packages for the HST instruments e.g. Pydrizzle and Multidrizzle.

STSDAS

STSDAS is the software for reducing and analyzing data from the Hubble Space Telescope. It is layered on top of IRAF and provides general purpose tools for astronomical data analysis as well as routines specifically designed for HST analysis. We currently have version 3.4 installed.

AIPS

AIPS, the NRAO Astronomical Image Processing System is used primarily for reducing data from synthesis radio telescopes. General information is given in the AIPS FAQ. We currently have version 31DEC06 installed.

MIRIAD

MIRIAD is radio interferometry data reduction package. It has particular emphasis on aspects of interest to users of the Australia Telescope Compact Array (ATCA). Miriad can be used for the reduction of continuum and spectral line experiments. Miriad, in particular, supports a number of niche areas. These include calibration and analysis of polarimetric data from the ATCA, multi-frequency synthesis imaging, mosaicing, ATCA pulsar bin mode, and some spectral line observing applications (e.g. Zeeman experiments).

SAS

SAS is the XMM-Newton Science Analysis System. We currently have version 6.5.0 installed.

IDL

IDL, the Interactive Data Language, or IDL, is a product of Research Systems Inc (RSI). It is a package designed to reduce, analyse and display scientific data and images. IDL can be used for tasks such as: Line drawing and fitting, contour and surface plotting, animation. Matrix operations, solving nonlinear equations, ffts etc. Writing functions and procedures. and much more. More extensive information is given in the IDL FAQ. Latest IDL version IDL 6.2 is now available under Solaris and Linux (with a very large number of floating licences).

TeXtoIDL

TeXtoIDL: The purpose of the TeXtoIDL routines is to make it simple to use Greek letters, subscripts and superscripts in making labels for plots in IDL. This is accomplished by allowing the user to use TeX control sequences for Greek letters and special symbols and for sub/superscripts. The TeX control sequences are simple and easy to remember, especially if you already use TeX for writing papers (for those unfamiliar with TeX, an explanation of that notation is below). The translation is done for either vector or PostScript fonts.

IDLWAVE

IDLWAVE: This package has been installed as part of Emacs to enable it to understand IDL syntax, which is very useful when writing IDL scripts. A number of lines should be added to your ~/.emacs file, and IDLWAVE online information which can be viewed with `M-x idlwave-info', or follow the Menu entry in the IDLWAVE menu. IDLWAVE also enables running an IDL shell within emacs - type:

M-X idlwave-shell

which runs your settup defined by the environment variable IDL_STARTUP.

Spitzer tools

Spitzer telescope observation preparation tool (SPOT). SPOT is the observation preparation tool for the Spitzer telescope. Leopard is the software package used to download data. A SPOT User Guide and Leopard User Guide are available. We currently have version Spitzer-pride13_0_3 installed.

Display/documents

  • LaTex (and all related packages, e.g., pdflatex, ps2pdf??, etc)
  • SM

Supermongo (sm)

Supermongo (sm) is a flexible graphics package. An on-line guide and sm tutorial are available. SM's great strength is that you can define macros to perform common tasks. SM can also emulate regular Mongo - to do this issue the command `compatible'. Examples of sm macros can be found in /data/system/user_guide/sm/. The version installed is sm 2_4_26

To run sm just type:

sm : quit

To get help type:

sm -help
