Scripts and Packages

Scripts

Analysis scripts allow users to extend the functionality of a software package by writing custom "tools" to fit their specific needs. This is especially true in the case of S-Lang, since CIAO provides such extensive support for the language.

There are a number of scripts written in S-Lang available from the Scripts page.

It is also possible to write Perl subroutines in S-Lang via the Inline::SLang Perl module, which is made available as contributed software. The module allows you to embed any piece of S-Lang code into Perl; see Calling S-Lang routines from Perl for more information and examples.

Packages

A package is simply a set of interrelated S-Lang scripts that are installed as a group. It is different than a module, which is a library of code that may be written in C, Fortran, or similar compiled languages.

There are a variety of packages available for use within CIAO:

SITAR

The S-lang/ISIS Timing Analysis Routines (SITAR) are a set of functions and subroutines designed to perform timing analysis of data.

evt2img

A simple interactive program that produces either a PNG or JPEG true-color (RGB) image from a Chandra event file.
