| | Spitzer Contributed Software: SMART |
For more information on SMART, please consult the following resources:We encourage users to read the available documentation and report any bugs they may encounter to the SSC Helpdesk (help@spitzer.caltech.edu). The SSC has staff that can answer most questions on SMART and can forward bug reports to the IRS team. (The SMART software is Contributed Software.)

IDL
SMART is written in IDL, and requires a licensed copy of IDL (version 5.5 or greater) to run. To download IDL and purchase a license, visit the ITT website. SMART does not currently run under the IDL Virtual Machine.
If you have IDL 6.x, there is a small additional complication. IDL 6.x has a Path Cache feature that is supposed to dramatically speed up searches for procedures in an IDL project. Unfortunately, SMART, with its dynamic path changes, is not compatible with this, so you need to disable the Path Cache in order for it to work. One way to do this is to insert the line
setenv IDL_PATH_CACHE_DISABLE
in the SMART script file, just under the first row of ######.
SMART includes certain publicly available IDL routines taken from Astrolib, The IDL Astronomy User's Library maintained at the NASA Goddard Space Flight Center. Please ensure that Astrolib is installed on your system before attempting to use SMART.
VERY IMPORTANT - Access paths on your system must be set so that SMART is accessed BEFORE Astrolib. Failure to do this will result in unpredictable results.
Perl
SMART includes scripts written in PERL (Programmable Extensible Report Language). If you wish to use these you must have PERL installed on your system.Once PERL is installed you must add to it the "CFITSIO" file subroutine library (which allows PERL to handle FITS files) and the "CFITSIO.pm" interface (which allows PERL to use CFITSIO). Information about both CFITSIO and CFITSIO.pm can be found at CFITSIO - A FITS File Subroutine Library (This is maintained by the NASA Goddard Spaceflight Center.)
Due to the very large number of possible system configurations, we cannot advise on how to install PERL, CFITSIO or CFITSIO.pm on any particular system. Please see your local system administrator for advice about how best to do this.
NOTE : PERL, CFITSIO and CFITSIO.pm are not necessary for basic running of SMART. They are only needed to use SMART scripting.
ATV
SMART includes a specially modified version of ATV. The SMART modified version of ATV requires an additional routine : cmps_form.pro. Please download this and place it in your default IDL directory. This allows it to be used by other routines.Laptops
Installing SMART on a laptop with a screen size of 15 inches or less can cause problems with the IDEA (ISAP) widgets. They are bigger than the screen and cannot be resized so the widget's buttons cannot be accessed, rendering the software unusable.
The current version of SMART is v6.4.0. The major change in SMART v6.4.0 is a new LH spectral extraction algorithm that matches the algorithm adopted by the SSC in IRS pipeline version S17.2. This allows the use of SSC S17.2 calibration files for LH data within SMART. For more information on additional improvements, see the current release notes.
Note that there is residual order mismatch in the two reddest LH orders in some datasets. This is inherent in the BCDs and is not produced by SMART. We are currently investigating the problem.
You will find gzipped tarfiles of both SMART and the most recent set of SMART calibration files here.
Here we outline the steps required to install and run SMART:
- If you have a previous version of SMART installed in $home/smart, do the following. Otherwise skip this step.
- cd to $home
- rm -rf smart (the -rf option does not prompt and removes subdirectories as well)
- Remove the smart_bin directory wherever it exists (typically it will be under your home directory).
- Remove old IRS calibration files which are under the directory $home/IRS_Calibration
- Download the tar packages to the "home" directory.
- Unpack the tar files by running these commands:
gzip -dc smart-[version number].tar.gz | tar xvf -gzip -dc IRS_Calibration-[version number].tar.gz | tar xvf -- Now you should have two directories: $home/smart and $home/IRS_Calibration. (Hereafter we assume that $home is /home/john).
- In your .cshrc file, change your IDLPATH environment variable to have these two directories as the first two items e.g.
setenv IDL_PATH +/home/john/smart:+/home/john/IRS_Calibration:+/usr/local/lib- To invoke your newly modified .cshrc file, type the following at your Unix prompt:
source .cshrc- Enter the smart subdirectory by doing
cd smart- Make the shell script writable and executable:
chmod 755 smart- Open the file "smart" in your preferred editor and edit the relevant environment variables between the #### : see figure
- Once SMART is installed the version number can be checked by viewing the read-only file "smart/smart_version.txt".
