Debian Astro GDL packages

IDL/GDL packages for astronomy

GDL (GNU Data Language) is a free replacement for the commercial software IDL (Interactive Data Language). It has full syntax compatibility with IDL 7.1 and is usable for astronomical data analysis. This metapackage will install astronomy related packages usable with GDL; especially the IDL Astronomy Users Library.

Low-level astronomy software for GDL

gdl-astrolib: Low-level astronomy software for GDL

Description

The IDL Astronomy Users Library is a central repository for low-level astronomy software written in the GNU Data Language (GDL). The library is not meant to be an integrated package, but rather is a collection of procedures from which users can pick and choose (and possibly modify) for their own use. Submitted procedures are given a cursory testing, but are basically stored in the library as submitted.

The library was originally written for the commercial IDL interpreter, but large parts are usable with the GDL interpreter as well. Other names for the libraries are "astron" and "idlastro".

The Coyote Library evolved from work David Fanning was doing teaching IDL courses and answering IDL questions on the IDL newsgroup. It is meant to be a well-documented library that demonstrates how to write solid IDL/GDL programs that are easy to maintain and extend.

The main content of the library is the Coyote Graphics System (CGS), a collection of Coyote Library programs that turn the traditional GDL/IDL graphics commands (e.g., Plot, Contour, Surface, TV, etc.) into modern programs.

The most important features of Coyote Graphics System are:

The commands work identically on the display, in PostScript, and in the Z-graphics buffer.
The commands can be displayed automatically in resizable graphics windows.
The commands automatically create high quality PostScript, PDF, and raster file output.
CGS graphics visualizations can be saved and restore later, or e-mailed to colleagues.
The commands work identically in an indexed or decomposed color environment.
The commands can use colors by name (e.g., "red", "dodger blue").
CGS commands are faster (often much faster) than the equivalent IDL function graphics commands.
Greek letters and other symbols can be directly embedded in Coyote Graphics text.
The commands fix the most annoying quirks (e.g., contour holes and levels) in traditional IDL commands.

gdl-mpfit

1.85+2017.01.03-4

Robust non-linear least squares curve fitting for GDL

gdl-mpfit: Robust non-linear least squares curve fitting for GDL

Description

These GDL routines provide a robust and relatively fast way to perform least-squares curve and surface fitting. The algorithms are translated from MINPACK-1, which is a rugged minimization routine found on Netlib, and distributed with permission. This algorithm is more desirable than CURVEFIT because it is generally more stable and less likely to crash than the brute-force approach taken by CURVEFIT, which is based upon Numerical Recipes.

MPFIT has additional capabilities not found in CURVEFIT. Model parameters can be "frozen" (that is, held constant during the fitting process). Simple boundary constraints can be imposed on parameter values, which can be helpful to keep parameters from becoming negative, for example. Please see the documentation for the PARINFO keyword if you wish to use this facility.

gnudatalanguage

0.9.9-10

Free IDL compatible incremental compiler

gnudatalanguage: Free IDL compatible incremental compiler

GNU Data Language (GDL) is a free IDL (Interactive Data Language) compatible incremental compiler. It has full syntax compatibility with IDL 7.1. IDL is a registered trademark of ITT Visual Information Solutions. From IDL 8.0, the following language elements are supported:

FOREACH loop
negative array indices
garbage collection pointers and objects
call methods on an object using "." (e. g. object.aMemberProcedure,arg1)

The file input output system is fully implemented. GUI support (widgets) is officially provided, but it's not complete yet.

This package contains the main commandline and interpreter frontend.
