Key to IRAS Point Source Catalogue Data Table Columns

All the data returned from the search are listed in tabular form on the results page. Any source tables found are listed first, followed by images. This help page explains the format and columns of the catalogue metadata table (standard flat ascii file in IPAC format).

Catalogue Metadata Table

The IRAS Point Source catalogue column header is as follows:

       |    pscname|  ra1950 | dec1950 |      ra |     dec |   fnu_12 |   fnu_25 |   fnu_60 |  
        fnu_100   |  fqual_12  |  fqual_25  |  fqual_60  |   fqual_100  |

Below is the key describing each column name found in the IGA Atlas IRAS Point Source catalogue metadata table. For more information on the IRAS Point Source catalogue, click here.
