[Geometry] Box [Definition] 
The box region is defined by the corners of the box and a center given in RA and Dec. The number of corners to describe the box is up to six and for each corner the RA and Dec is provided. In a few cases, Laros et al. (1998) report "hybrid" boxes which are based on either the IPN and the BATSE-only or COMPTEL-only error regions were used. These hybrid boxes are defined by segments of one of the IPN annuli and an area.
