It is possible to run the simulation with different schemes for detecting sources in the simulated images. The task eimsim calls a separate script to perform the source detection. The user may either select one from the (small) range available, or supply their own. It is usually also necessary to supply a matching `preparation' script to eimsimprep. Exact details of the necessary calls can be found in the documentation for these respective tasks. In `cookbook' terms however, the two styles appear as follows:
eimsimprep dettype=2xmm eimsimbatch eimsimreduce
eimsimprep detpreptask=<name of my det prep task> eimsimbatch dettask=<name of my detection task> eimsimreduce
Of course you can also use this command style to run one of the supplied detection schemes if you wish. If you do this you will find that there is some protection in place to prevent you running clashing preparation and detection scripts. You will also be warned if you try to use a 1xmm template set with 2xmm detection scheme, for example.
