Comments on Difmap processing
J0609-15/J1256-05 (1.7/7 Jy) look fine for Ka, Sh, Mo. J1159+29 (1.8 Jy) implies Kal needs increasing by at least factor of 2.

On J1051+21 the radpl agrees with UNSO (8GHz) 40 days later -- which is very different to ones of '95 & the PLS of '96. Image is of a core extended along NW direction, USNO looks like SE direction.
