1. Polarizer Quad Filter
The polarizer quads were also designed to map onto a four-faceted WFC configuration and, consequently, also require a partial filter rotation of -33њ to move the filter quadrant 1 (nominal polarization angle 135њ) into WFCs 2 and 3, with some vignetting of both camera fields. Several additional partial rotations have been added to allow observations with different polarization angles on the same CCD. ... Table 3.10: Polarizer Quad Filter. ... Filter Name . ... Nominal filter wheel position . ...

11. Descriptor NFILTCAR
... NFILTCAR is the logical rather than the physical number of carriers; if two or more filter wheels are encoded as a single character in the data, there is effectively only one filter wheel, as far as data handling is concerned. If one filter mechanism carries chromatic filters and another carries ``neutral'' filters, the total number of bands (i.e., rows) in the table should be the product of the number of positions in the two carriers. ...

14. Spatial Region Boundaries
Describes how spatial region boundaries are handled. The golden rule for spatial region filtering was first enunciated by Leon VanSpeybroeck in 1986: . ... With this in mind, the rules for determining whether a boundary image pixel or table row are assigned to a region are defined below. For image filtering, pixels whose center is inside the boundary are included. ... That is, an row is inside the boundary without regard to its integerized pixel value. ...
