SMART Release

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.

Downloading SMART

"I used AdOpt [Adaptive Optimal Extraction] a few weekends ago to extract a spectrum and it is amazing! Everyone should try it!" -- A happy SMART user, 17 November 2009.

[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..." -- Another happy SMART user, 16 November 2009.

To install SMART you must download and unpack two separate tarballs. Full instructions about installing SMART on your system are given in the Installation Guide.

• Download SMART v8.0.3 (23Mb) (30 October 2009) and the associated Calibration Files v1.7.1 (12Mb) (15 October 2009). Smart v8 includes in particular optimal extraction, multiple source extraction, complex backgrounds. See Optimal extraction documentation.

• Make sure you have the latest version by clicking on Help->Check update in the main window

• Version history and scheduled updates

• Important note: The version 8.0.0 released the 9th of October 2009 contained a bug in the flux calibration (optimal extraction). Also, the flux calculated for sources offset in the dispersion direction (the on-the-fly PSF was created correctly, resulting in a good fit, but the flux level was wrong). Version 8.0.1 corrects these issues. The new calibration file package should also be downloaded.

Notes about the calibration files

• The calibration files tarball contains the SSC supplied Calibration files used by Smart up to and including version s18.7.

• The calibration files tarball is updated to include the latest calibration file releases provided by SSC. Even if there are no changes to SMART software it is necessary to ensure that you have an up to date set of calibration files. For this reason please check this page periodically and ensure that you always have the most recent version of the calibration files.

• The official Smart Calibration Files package contains only the files used by Smart. For custom extractions using other calibration files, please download also the Full Package v1.6.0 (21Mb). This optional calibration files tarball contains all the SSC supplied Calibration files up to and including version s18.7. Important note: the files are not ordered by sub-directories in this package, and darks are not included.

Citing SMART

We request that authors using data from the IRS and/or the SMART software include the following acknowledgements and citations in their papers :

• SMART: SMART was developed by the IRS Team at Cornell University. The most important and recent changes relevant to spectral extractions (including the optimal extraction GUI "AdOpt") are described in Lebouteiller, Bernard-Salas, Sloan & Barry, arxiv0910.1846, 2009. "Advanced Optimal Extraction for the Spitzer/IRS". Publications presenting extractions performed in SMART should cite this reference along with the original SMART paper: Higdon et al., PASP 116, 975-984, 2004.
