This table is an associated to the GRBs Catalog and lists the parameters that defines the box region derived from the intersection between the IPN annulus and a region from a different observatory. For a given GRB the localization can be provided by different observatories with different region types or by the same region type with different parameters. The different region types reported in literature are the following: circle, annulus, box, dual, annulus intersect, irregular, and intersect. This table contains the description only for the region type intersect, the other types are stored in separate tables. This localization region consists of a box derived from the intersection of the IPN annulus with the region determined by a different observatory. The table lists the corners of the final box intersection and the parameters that defined the IPN annulus (center, radius and half-width). The region of the other observatories that intersect with the IPN annulus is listed with the record for this GRB associated with the other observatory. The measurements are reported as found in literature and any differences or remarks are included in one of the table parameter (localization_notes). The literature references are provided in the GRBs Catalog main table which is linked to this region table. This table was ingested by the HEASARC in June 2008 based on electronic versions obtained from the author(s), who compiled the catalog in 2005. This is a service provided by NASA HEASARC .
