1. Apertures
Optical Filters . The WFPC2 camera configuration and filter set require a substantial number of apertures for full utilization of its capabilities. ... An additional set of aperture names have been defined for use with the WFPC2 filters which require partial rotations. ... The pixel coordinates of these apertures will be reviewed on a regular basis to reflect changes in CCD and filter cosmetics. ... The aperture name is generally the same as the (rotated) filter name. ...

... Matrices and their invariants, such as order, rank, determinant, play an outstanding role in mathematics. ... To be a little more precise, nonzero square matrices of order $r+1$ (modulo multiplication by a nonzero constant) are represnted by points of the projective space $\Bbb P^{(r+1)^2-1}$. Geometrically, we consider the subvariety of matrices of rank one which is just the Segre variety $S=\Bbb P^r\times\Bbb P^r\subset\Bbb P^{(r+1)^2-1}$. ...
