FAINT_POINT_SOURCE

The FAINT_POINT_SOURCE recipe is used to reduce observations of point sources that are faint enough that they may not be detected in the beam detection. In this case, the locations of the beams as determined for the standard star are used to extract the object. Optimal extraction is still used.

The following variants are available: FAINT_POINT_SOURCE_NOFLAT (no division by a flat-field), FAINT_POINT_SOURCE_NOFLAT_NOSTD (no fivision by a flat-field and no extraction of an arc spectrum), and FAINT_POINT_SOURCE_NOSTD (no extraction of an arc spectrum).
