4.6 Filling out the IRAC AOT

We now fill out the IRAC AOT, starting with selecting the AOT type. This is accomplished either by selecting ``IRAC Mapping'' from the ``Observation'' pull-down menu, or by clicking on the ``Infrared Array Camera $3.6 - 8.0 \; \mu {\rm m}$ imaging of single or multiple fields'' icon (the blue checkerboard icon, sixth from the right on the icon taskbar). The IRAC Mapping AOT entry window will appear as illustrated in Fig. 4.7.

Figure 4.7: The IRAC Mapping AOT entry dialog.

The IRAC AOT itself consists of an (optional) dither pattern superposed on an (optional) rectangular-grid raster. In this section, we will discuss each of the AOT entry options, and the activities that the spacecraft and telescope will perform when the specified AOR is executed. Let us consider these in turn.
