Need Data? Use the Spitzer Heritage Archive (SHA)

Spot is a software package for Spitzer observers to plan observations, and Leopard is a software package once used to query and download data from the archive. Since November 2010, Leopard can only be used to search through all planned and executed observations, i.e., to search the Reserved Observations Catalog. (NB: All data downloads must now be performed using the Spitzer Heritage Archive). Together, this group of cats is referred to as the "Spitzer Pride."

Spitzer Pride Software

Installation Files Size To Install the software
  • Click on the link and save the program to disk
  • Run the program (double-click on it) to install it
  • It will create two programs: spot and leopard
  • You will need administrator privileges to install under Vista
  • Please note: The Windows installer does work, but you may see some errors if you don't have Java 1.6 pre-installed.
  • Please see important notes below.
  • Click on the link and save the program to disk
  • To make the program executable type: chmod +x
  • To install it type: ./
  • It will create two programs: spot and leopard
  • Please note: The Solaris auto-update may take some time because it is going to download and install Java version 1.5. If you cancel the installation before it is complete, you will have to install Spitzer Pride from scratch by downloading the S18 software.
  • Please see important notes below.
  • Click on the link and save the program to disk
  • To make the program executable type: chmod +x
  • To install it type: ./
  • It will create two programs: spot and leopard
  • If using a 64-bit machine, please see the Linux note further down this page.
  • Please see this note regarding running Spot with Java 1.8
  • Please see important notes below.
Mac OS X

Remember to download the documentation for Spot and Leopard as well as the software! If you find a bug, check the known bugs list for Spot or Leopard and if we don't already know about it, please submit a bug report.

  • Leopard is still the way to search the ROC because it includes all planned and completed observations. The Spitzer Heritage Archive only includes infomation about completed observations.
  • Spot and Leopard v19 are the current software versions. To get version 19, download v18 and ensure that Options -> Auto-Update is selected in Spot/Leopard to obtain an automatic update of the software
  • Only the latest version of the software can connect to the servers at the SSC.
  • If your system does NOT auto-update, then you DO NEED to do a fresh install of S18 and auto-update to the latest version
  • Spot requires JAVA version 1.6 or 1.7. It does not work with version 1.8. Prospective GO investigators are strongly encouraged to download Spot and to start planning their observing programs well before the proposal submission deadline. Allow Spot to auto-update to the latest version (Options => Use Automatic Spot Version Update), if you have not already. If you use Linux and JAVA version 1.8, we recommend you download Spot for Linux from the Proposal Kit webpage and do a clean re-install, then let Spot auto-update.

For Linux Users:
If you see the error " Unable to complete Submitting Proposal: a network error occurred." when submitting a proposal on Linux:
This error can occur for Linux users who are using much more recent java installations and/or 64-bit computers. Please also see this note regarding running Spot on Linux with Java 1.8. Please see the "Java Runtime Notes" section below for more information on using Spot on 64-bit Linux

Java Runtime Notes:
If you decide to use a different Java Runtime Environment than is provided by our own installers, or are running on a platform other than our standard installations (this, e.g., applies to Linux 64-bit machines), then you should use this 'generic' installation: First, obtain (or locate) your own local Java 1.6.x installation. Then, click on the link here and save the program to disk. To make the program executable, type: chmod +x Finally, to install it, type: ./ The installation script will ask you for the explicit path to your Java directory. Or, alternatively, you can run the programs thereafter by typing, e.g., for Spot: spot -jre <JRE_DIRECTORY>. Please note that after the upgrade from v18 to v19, Spot will be broken unless you always provide the -jre flag and the correct java path. Please see this note about upgrading from v18 to v19. For more information on this, see the Spot and Leopard documentation.

Find a bug?
Have you found a 'feature' in Spot or Leopard? If you think you have found a bug, before reporting it please check this list of known bugs in Spot, this list of known bugs in Leopard, read the Release Notes for Spot and Leopard, and the applicable sections of the Spot User's Guide and Leopard User's Guide. It may be a "feature" we already know about.

If you have found a real bug then please do let us know by sending the following information to the Spitzer Helpdesk:

  • Your name
  • Your email address
  • Your type of computer (PC, Solaris, Linux, Mac,...)
  • Your operating system (Windows 2000, Solaris 2.5, Mac OS 10.2, ...)
  • Your windowing system (CDE, Gnome, ...)
  • Description of bug
  • AOR file
  • Spot or Leopard log file (see below)

Spot and Leopard Log Files - Each time you run Spot it creates a file called 'spot-DATE_TIME.log', and analogously for Leopard. It can be found in the default directory created when you install the software. The default directories (for both Spot and Leopard) are:

Windows 95,98,MEC:\spot
Windows NT,2000,XPC:\Documents and Settings\{username}\Application\Data\spot
Windows Vista,7C:\Users\{username}\Application\Data\spot
