Notes.
Deconvolved average diameter, calculated assuming that the cores are Gaussians
from the expression 
, where
FWHM = 
, with A the area inside
the polygon corresponding to the contour at half maximum, and HPBW is the
synthesized beam.
Associated with the centimeter continuum source CM2, α(J2000) = 18h54m00
