The IRASID database contains the associations data for the IRAS Faint Source Catalog (FSC). The main catalog of non-associations data is contained in the IRASFSC database.

Parameters

Name
The IRAS source name.
Record_Number
The record number in the main IRASFSC database.

Catalog_Number
The number of the association catalog.  The key to the catalog number
references and their interpretations is available from the HEASARC.

Source
The name of the source in the association catalog.

Type
The source type or spectral class, if available.

Radius
The radius vector from the IRAS source to the association.

Position_Angle
The position angle from the IRAS source to the association.

Major_Dist
The distance from the IRAS source to the association along the IRAS position
error major axis.

Minor_Dist
The distance from the IRAS source to the association along the IRAS position
error minor axis.

First_Field
Object field #1 is catalog dependent and may reference a magnitude or some
other parameter.  The key to object field codes for each catalog referenced is
available from the HEASARC.

Second_Field
Object field #2 is catalog dependent and may reference a magnitude or some
other parameter.  The key to object field codes for each catalog referenced is
available from the HEASARC.

Third_Field
Object field #3 is catalog dependent and may reference a magnitude or some
other parameter.  The key to object field codes for each catalog referenced is
available from the HEASARC.
