Retrieving Spitzer data with Leopard

  1. Start up Leopard.

  2. Click on the "Q" button for "query," and search by position or program id to obtain whatever data you want. Alternatively, choose search by "AOR id query" from the file menu and enter the AORKEY. For this example, search on a Pleiades star, HII 173. This name is resolved successfully by Simbad when you interactively use Simbad, but it's too obscure for the automatic name resolver. So, to find these data, you can do any of the following: To further refine your search, turn off IRAC and IRS data; search only on MIPS data. Depending on how you search, you may be presented with multiple PIDs to select from. For this example, choose PID 148.

  3. Find the AOR you want in the list of returned AORs. For this example, the one you want has a label (AORLABEL) of 'MIPS-S179'.

  4. Select the wavelengths you want, and the kind of data you want. Click on the little diskette icon to begin the download. It will launch something called the "Subscriber" to manage the download. For this example, select at least 24 and 70 wavelengths (here 160 is all serendipitous data, but you can select it anyway), BCD and Post-BCD data to download. With all three wavelengths, it totals ~35 M. (see figure of Leopard screen below.)

  5. Wait for the download to finish. The Leopard subscriber is smart enough to pick up where it leaves of if there is a network hiccup mid-transfer.

  6. Unzip the files that Leopard puts on your disk. For this example,
    unzip P0148-_MIPS-S179-part-01.zip
    unzip P0148-_MIPS-S179-part-02.zip
    unzip P0148-_MIPS-S179-part-03.zip
    unzip P0148-_MIPS-S179-part-04.zip

  7. What are all these files? Check out these pages:

Obtain AOR using Spot (optional but useful if truly new at this)

This program (pid 148) happens to be a huge program so either one of these approaches will work:

Once you have the AOR, use Spot's visualization capability (see the Observation Planning Cookbook, nearly any chapter, for step-by-step instructions; the results are in the figure below) to visualize your AOR. Each one of the frames you see portrayed in the visualization results in a DCE, or Data Collection Event, or a set of files on your disk. For a discussion of which files are most important, see the MIPS DH. There are also pages with the filenaming convention defined: MIPS-24, MIPS-70.
