Retrieving Spitzer data with Leopard

Start up Leopard.
Pull down the Query menu and select By Position or By Program to obtain whatever data you want. Alternatively, select By AOR ID from the Query menu and enter the AORKEY. To find these data, you can therefore do any of the following:
- Query By Position, type in the target name, and use Simbad to resolve the name.
- Query By Position via manually entering the coordinates. HH 46, according to Simbad, is at RA 8h25m43.90s, Dec -51d00m36.0s (J2000)
- Query By Program. The Early Release Observations program with this observation is pid 1063.
- Query By AOR ID. Enter AORKEY=7130112.
To further refine your search, turn off MIPS and IRAC data; search only on 'All' IRS data. Depending on how you search, you may be presented with multiple PIDs to select from. For this example, choose PID 1063.
Find the AOR you want in the list of returned AORs. For this example, the one you want has a label (Label) of 'hh46src.'
Select 'all wavelengths' 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 the BCD data to download (the Post-BCD data can also be downloaded, but for IRS they are only useful for 'quicklook' purposes). We might also want the calibration ('Cal') data that went along with the most recent pipeline processing of the spectral image data. The total data volume of BCD and cal files is approximately 49.2 M.
Unzip the file that Leopard puts on your disk. For this example,
```
unzip P01063-_hh46src.zip
```

Visualizing the AOR in Leopard

You can follow these steps:

Be sure that the AOR is still highlighted in Archive Query Results window in Leopard
Select an image on which to overlay the AOR; go to the Images menu and, e.g., select the 'DSS Image' option.
In the DSS Image dialog, select a survey type; in this example, we've selected 'POSS2/UKSTU Red.' Also select an image size; in this example, we've selected an image with equal width and height of 0.25 degrees.
To show the target position, select from the Overlays menu the 'Current Fixed Target' option.
To overlay the AOR, select from the Overlays menu the 'AORs on current image' option. Then, select the 'Current AOR' in the 'Which AORs' dialog window.

The AOR overlay should look like what's shown below 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 IRS Data Handbook.
