Hi there. I have a question regarding JMFIT. If I fit a point source using 
GWIDTH=0 and DOWIDTH=-1, the deconvolved size is (correctly) reported as 
0.0. If I repeat the fit exactly as before, but this time with BWSMEAR set 
to a non-zero value, the deconvolved sizes are no longer exactly equal to 
zero. They are very, very small, but not zero. I was wondering if this was 
the expected behaviour.
