Here are some common definitions. The archive of Spitzer data is the Spitzer Heritage Archive (SHA). An individual Spitzer observation sequence is an AOR, or Astronomical Observation Request. In certain cases (often calibration or sometimes science observ...
In the "Search Catalog" pane, click on the "Set Column Restrictions" link in the lower left. At the top of the dialog box that pops up, select the "Long Form" menu item. Then click "OK" and "Search".
For Mac versions starting with Lion and some settings of Gatekeeper, you may receive the following error message when you attempt to run Mopex: "Mopex" is damaged and can't be opened. You should move it to the Trash. Click "Cancel". You will need t...
As part of the closeout for the Spitzer cryogenic mission custody of Spitzer documentation was transferred from the Spitzer Science Center to the Infrared Science Archive (IRSA) in April of 2011. However some information needed to run the warm mission was...

The red-shaded data are still proprietary. If they are your data, then log in and you should be able to download them. If they are not your data, you can download those data after the data become public, usually about 12 months after the data were taken (...
Click on the checkbox at the top of the column of checkboxes, at the top left of the search results pane.
Yes, there are a lot more files than what are shown, such as the errors! We decided for clarity that only certain files of primary interest to users would appear for individual examination in the SHA interface, but of course the download includes many mor...
Sometimes, if there is a network hiccup (e.g., you pick up and move your laptop to a different wireless hub), the SHA can be left in a funny state. To avoid this, if you've accomplished a complex search, log in to the SHA and save or tag the search. That ...
When downloading large quantities of data (big programs, whole campaigns, etc.), the SHA will break up the downloads into "manageable" pieces, where "manageable" is defined as "not larger than common computers and software can handle." We understand your ...
72 hours, sometimes longer if the SHA is not under heavy use.
Each of the instruments (IRAC, IRS, and MIPS) has an Instrument Handbook, which lists and defines each of the files. They also describe instrument artifacts, and give guidance as to how to reduce the data.
If the data was taken in IRAC's subarray mode, or for certain IERs (Instrument Engineering Requests), there will be no post-BCD data for the observation. Data in IRAC subarray mode are not processed through the online post-BCD pipeline. The post-BCD pipel...

We don't currently have any special Mopex/Apex namelists for crowded fields. Many people have used the default namelists. If using the GUI, see Cookbook Recipe 7, http://irsa.ipac.caltech.edu/data/SPITZER/docs/dataanalysistools/cookbook/7/ [1]. And the...
To uncompress the files you have downloaded from the command line, type "unzip .zip". To uncompress multiple files at once, type "unzip '*.zip'" (the single quotes are important), or "unzip \*.zip" -- you just have to escape out the wildcard. Double...
Yes. The IRSA YouTube channel [1] has several tutorials on archives housed at IRSA -- there are playlists organized by archive as well as a set of "micro-tutorials" relevant for more than one archive. The videos are in HD; you may need to manually use the...

For Mac versions starting with Lion and some settings of Gatekeeper, you may receive the following error message when you try to run SPICE: "spice" is damaged and can't be opened. You should move it to the Trash. Click "Cancel". You will need to te...
Here are some tips for making your large catalog search return faster: 1. If you suspect that your query might return results larger than 2 Gb, you will need to break it up into smaller queries. It can be difficult to predict the size of the returne...
The IRSA GLIMPSE holdings include Catalogs and Archives. The Catalog is a MORE RELIABLE list of sources, and the Archive is a MORE COMPLETE list both in number of sources and flux measurements at each wavelength (less nulling of fluxes). Vizier has concat...
To retain only the most robust flux densities, apply the following cuts: 1. Make a SNR cut. Each source has 5 columns ending in "FluxType", four for each of the IRAC channels and one for MIPS-24. Flux densities directly detected in an image with SNR...
