8.5 Filling in the AOT using Spot

We begin with the two target fields with low background. We go through the AOT for Abell 2218 in detail, and then we can simply copy it for Abell 665. Then we will use fixed cluster targets to specify a few individual pointings in each of the medium background galaxy clusters; again, we will go through one in detail. The other would be very similar. Finally, we will do a single, deep pointing in the high background cluster. Note that in each case we only select $16 \mu {\rm m}$ imaging, but $22 \mu {\rm m}$ data will also be obtained at a spatially offset field. These extra data are not useful in this case, as there will be deeper MIPS coverage, but they might be important to other programs (or cause duplication problems for our program, see above).

The AOR file is listed in the Appendix here and is also available on the website, ready to be loaded into Spot:
