Sources that are optically thick at 43 GHz will have higher proportions of their total flux in an unresolved core at 86 GHz, while those that are optically thin at 43 GHz should have about the same fraction in the core at 86 GHz as at 43 GHz.

...1998).
Note that observed brightness temperatures are reduced by a factor of (1+z) from the brightness temperatures in the source co-moving frames; at a typical blazar redshift of z=1, the brightness temperature at the source redshift would need to be 29#29 K in order to yield an observed value of 30#30 K.

Note that this list contains several gravitationally lensed sources; no attempt has been made to account for the fact that lensing permits better intrinsic resolution in those objects.
