## GRBCATINT - Gamma-Ray Bursts Catalog: Intersect Regions |
HEASARC Archive |

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.

**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.
