Notes. Description of columns: 1) telescope name; 2) the telescope half power beam widths; 3) a 3 character code to identify each telescope.

^(†)

The N-S extent of the Nançay beam changes with elevation, however, as this dimension is always much larger than any of our galaxies this term can be safely neglected in the beam correction factor.
