Spectral Analysis Tools

A blog post on October 2, 2009 received a lot of responses all describing different spectral analysis tools people use.  This page is to track as many of them as possible and compare their capabilities / benefits / shortcomings.

 

Spectral Analysis Tools
 Name  Capabilities Shortcomings
 IRAF (NOAO)   hard (impossible?) to script?
DIPSO (STARLINK)    
 CLASS (GILDAS)    
GBTIDL (NRAO)    
CASA (NRAO)    
Gandalf 2d IFU  
Profit    
SpecPro

Interactive IDL-based program for viewing and analyzing galaxy spectra. Auto redshift determination.

IDL. Designed for galaxies, not for stars. Doesn't measure EWs.

PySpecKit Interactive & automated python-based toolkit for displaying and fitting profiles to spectra.  Deals well with units, extensible.  Easy to script. Measures EQWs. No template fitting; not good for stellar type determination.

astropysics.spylot 

and 

astropysics.spec

Python spectrum library and GUI viewer app (uses traits). Designed for scripting as needed. Not very automated.
