Yes. The IRSA YouTube channel [1] has several tutorials that are relevant to the SHA -- see the Spitzer playlist as well as the set of "micro-tutorials" relevant for more than one archive. The videos are in HD; you may need to manually use the YouTube gea...
This is a multi-step process at least at the moment. Check the header of one of your BCD files and look for the keyword 'CREATOR'. (e.g., imhead blah_bcd.fits | grep CREATOR) This is the software version used to process your data. Check the pipeline h...
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 ...
Click on the checkbox at the top of the column of checkboxes, at the top left of the search results pane. Then click on "Prepare Download."
Instructions on how to access your data can be found on the Data Archives page.
72 hours, sometimes longer if the SHA is not under heavy use.
It can vary, but up to 3-4 weeks. See the page on how the Archive works.
This answer comes in two parts: How to reference a Dataset ID in your journal articles Guidelines for publication acknowledgments.
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. (In some extreme cases, you will need to not just restart the browser but clear your browser cache.) To avo...
To grant someone else access to proprietary data, the primary investigator (PI) of the program should contact the Spitzer helpdesk (help@spitzer.caltech.edu) and ask that the person be granted access. Please include the following information: Grantee's f...
No, your _program password_ (aka "Spot password") is not the same as your _archive password_, sorry! If you want to access publicly accessible data through the archive, you do not need a password. If you want to access proprietary data through th...
The visualization tools currently only allow you to create 3-color images that you load from disk or from the web. If you want to create 3-color images using Spitzer data, download the data to disk and then load them into the SHA from disk as individual c...
The red-shaded data are still proprietary. If they are your data, then log in and you should be able to download them. (If you need to create a new account in order to log in, you may have to interact with the Spitzer Helpdesk to get your new account tied...
We have database blocktime every Thursday from 8 to 10 AM Pacific time. You may not be able to retrieve data or view programs during this time because the archive servers are down.
This is a known display issue with Leopard. It applies to IRAC Post-Cryo AORs only. If you need to know the pipeline version of post-cryo AORs, please double click on the AOR to open the Detail Information window, which will display the pipeline version.
This bug happens when using Leopard to find warm mission post cryo mapping programs. If you de-select IRS and MIPS in the Query: By Program dialog, no warm mission programs will be returned. Fix: Select all three instruments in the Query: By Program di...
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 ...
The pbcd products available from the archive were originally intended as quick-look images of your data. Post-BCD products have been produced with generic namelists, and the parameters have not been optimized for your data set. Post-BCD products and Level...
To uncompress the files you have downloaded, 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-clicking on the zipfi...
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 obs...
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...
Subarray mode is useful for observing very bright sources and/or observing with high temporal resolution. In subarray mode, only one corner, 32×32 pixels offset by 8 pixels from the edges, is read out from one array. Pixels (9:40, 9:40) of the array ar...
Here are links to pages for each instrument with the filename conventions and contents spelled out: * IRAC filenaming scheme [1] - see Section 6.1 * IRS filenaming scheme [2] - see Section 6.1 * MIPS filenaming scheme [3] - see Section 6.2, 6.2.1...
In a nutshell, DATE_OBS is the most accurate, absolute measurement for comparing with astronomical emphemerides. SCLK_OBS (in real sec) is good for relative timing comparisons within an AOR or even a campaign. More words on this: * DATE_OBS value...

Pipeline products after S18.5 no longer provide dmasks as they contain misleading and incomplete information. They have been superceded by the information contained in the the imask files. The imasks are more robust, include flagging of various artifacts ...

Leopard is now retired as the Spitzer archive interface. The primary place where you should be downloading Spitzer data is now the Spitzer Heritage Archive (SHA), which is resident at the NASA/IPAC Infrared Science Archive (IRSA) at the Infrared Proces...
