GRBCATINT: Help

GRBCATINT - Gamma-Ray Bursts Catalog: Intersect Regions


Overview

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.


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.

Int_Ann_RA
This is the Right Ascension corresponding to the center of the annulus given in units of degrees.

Int_Ann_Dec
This is the Declination corresponding to the center of the annulus given in units of degrees.

Int_Ann_Radius
This is the radius of the annulus defining the error region given in units of degrees.

Int_Ann_HW
This is the Annulus radius half-width (in degrees).

Int_Box_RA1
This is the right ascension of the first corner of the intersection resulting error box given in units of degrees.

Int_Box_Dec1
This is the declination of the first corner of the intersection resulting error box given in units of degrees.

Int_Box_RA2
This is the right ascension of the second corner of the intersection resulting error box given in units of degrees.

Int_Box_Dec2
This is the declination of the second corner of the intersection resulting error box given in units of degrees.

Int_Box_RA3
This is the right ascension of the third corner of the intersection resulting error box given in units of degrees.

Int_Box_Dec3
This is the declination of the third corner of the intersection resulting error box given in units of degrees.

Int_Box_RA4
This is the right ascension of the fourth corner of the intersection resulting error box given in units of degrees.

Int_Box_Dec4
This is the declination of the fourth corner of the intersection resulting error 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.
