The quadrant filters pass light in four discrete bands in different quadrants of the detector. These may be selected just like any other filter, but the selected filter will only produce data in one quadrant of the detector, and the image will contain data from all four quad filters in that slot. Exposures with a quad filter must be done with the UVIS-QUAD, UVIS-QUAD-FIX or UVIS-QUAD-SUB aperture.
