There are three basic recipes available for reducing science target observations: EXTENDED_SOURCE, POINT_SOURCE, and FAINT_POINT_SOURCE. These three have many variants that dictate the use or lack of calibration data. For example, there exists a POINT_SOURCE_NOFLAT recipe that is meant to be used for point source reduction without flat-fielding. The use of these variants is typically avoided, as the basic recipes can often flag uncalibratable data.
In addition, dual-beam polarimetry can be reduced using the POINT_SOURCE_POL recipe. This recipe is a variant of the POINT_SOURCE recipe.
