SMART, the "Spectroscopic Modeling Analysis and Reduction Tool," is a software package to reduce and analyze data from the Infrared Spectrograph (IRS) on the Spitzer Space Telescope. Updates/downloads
are provided on this web page from the development team at Cornell University.
"I just love the new version and the optimal extraction -- great job, thanks a lot!" --
"I used AdOpt [Advanced Optimal Extraction] a few weekends ago to extract a spectrum and it is amazing! Everyone
should try it!" --
[Re: super-resolution extraction] "I didn't know that (super-resolution) was going into this version! B and I have
always wanted to have all the sampling back..." --
- New version Download SMART package v8.2.9 (Sep 30, 2014). Note that if you changed the location of your user parameter directory (smart_bin) for previous installations (located by default in the smart/ directory), you should remove it before running the new version. Full instructions about installing SMART on your system are given in the Installation Guide.
We request that authors using data from the IRS and/or the SMART software include the following citations in their papers :
Should I use SMART or CASSIS?
SMART is a reduction and analysis tool with many features to manage various data products from the IRS (and other instruments, e.g., ISO), extract spectra in multiple ways, and examine spectra in details (fringes, fit of spectral features, black body fitting, etc...). SMART allows extracting spectra of complex objects (multiple, blended, with an extended background emission, etc...). The list of possibilities within SMART is too long to list here.
is an atlas in which spectra have been reduced and extracted automatically. The extraction method is selected automatically based on the source extent, providing a publication-ready spectrum.
- Spectral extraction: if the spatial structure of the source doesn't have to be decomposed and if the source is less extended than the aperture, users are encouraged to use CASSIS spectra. We advise users to explore the various diagnostic tools available on the CASSIS website to judge the quality of the extraction.
- For any other use than investigating a spectrum (e.g., to view IRS detector images, perform specific tasks like line fitting), and in particular to extract spectra of complex sources, users are encouraged to use SMART.
