4.9 Duplicating the A2218 AOR to Design the Complete Program

Finally, we need to duplicate this AOR for all of our other targets. To do this we can use the AOR replication tool. Click on the ``Edit'' tab, and select ``Copy current AOR.'' In the main Spot window, a second AOR, appearing to be exactly the same as the first we just created, will appear. Double click on it to edit, and the IRAC Mapping AOT entry dialog will appear. We need to change the target for this AOR, so we click on ``Target List'' which brings up a pop-up window with the list of targets we entered earlier (see §4.3). Select, for example ``Abell 1689.'' Also, adjust the AOR Label to whatever you like (e.g., ``IRAC Mapping: a1689 central position''). Hitting ``OK'' returns you to the main Spot window with the new AOR listed.

We repeat this procedure for all of the targets in the list and recalculate the duration necessary for the entire program. A screen capture of the main Spot window after all of this has been completed is shown in Figure 4.21.

That's it! Don't forget to save both the target and AOR list (otherwise all of this work will be lost when you exit Spot). For reference, we show the raw text .aor file for this set of observations (as well as the companion MIPS observations, developed in the next chapter) in Appendix B. For reference, the raw text .aor file for this set of observations is available at the SSC website:

In the next chapter (§5) we describe how to develop a complementary observing program to image the same fields from 24 to 160 microns, using the Multiband Imaging Photometer for Spitzer.
