GRBCATBOX - Gamma-Ray Bursts Catalog: Box Regions

HEASARC
Archive

Overview

This table is an associated to the GRBs Catalog and lists the parameters that define the localization region if the region is a box. 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 box region type, the other types are stored in separate tables. 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. The measurements are reported as found in literature and any differences or remarks are included in one of the table parameter (local_notes).

The literature references are provided in the GRBs Catalog main table which is linked to this region table.


References

References for the individual records in this table are available in the "reference" field of the GRBCAT main table.

Provenance

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.

Parameters

Record_Number
This is a numerical value that uniquely identifies a record within this database.

ID
This is a unique numerical value assigned to each GRB. Since for a given GRB there can be more that one record, this numerical value is assigned to all record associated to a specific GRB.

Name
This is the name of the GRB. The name are assigned following the "GRB YYMMDD" or "GRB YYMMDDn" if multiple bursts occur within a day, where n is a character string.

Box_RA
This is the Right Ascension corresponding to the center of the box region given in units of degrees.

Box_Dec
This is the Declination corresponding to the center of the box region given in units of degrees.

Box_Area
This is the area of the error box region given in units of arcmin2.

Box_Arc_Seg
This is the Segment length of IPN Annulus (in degrees).

Box_RA1
This is the right ascension corresponding to the first corner of the box given in units of degrees.

Box_Dec1
This is the declination of the first corner of the box given in units of degrees.

Box_RA2
This is the right ascension corresponding to the second corner of the box given in units of degrees.

Box_Dec2
This is the declination of the second corner of the box given in units of degrees.

Box_RA3
This is the right ascension corresponding to the third corner of the box given in units of degrees.

Box_Dec3
This is the declination of the third corner of the box given in units of degrees.

Box_RA4
This is the right ascension corresponding to the fourth corner of the box given in units of degrees.

Box_Dec4
This is the declination of the fourth corner of the box given in units of degrees.

Box_RA5
This is the right ascension corresponding to the fifth corner of the box given in units of degrees.

Box_Dec5
This is the declination of the fifth corner of the box given in units of degrees.

Box_RA6
This is the right ascension corresponding to the sixth corner of the box given in units of degrees.

Box_Dec6
This is the declination of the sixth corner of the box given in units of degrees.

Local_Notes
This field contains notes regarding the localization of the GRB. This is filled to explain how the values reported in the database are compared with the values reported in the literature.
