Example:

# Note: It's best to channel average the data if there are many channels before running a modelfit
split('ngc5921.ms','1445+099_avg.ms', datacolumn='corrected',field='1445*',width='63')
 

# Initial guess is that it's close to the phase center and has a flux of 2.0 (a priori we know it's 2.47)
uvmodelfit('1445+099_avg.ms', # use averaged data
           niter=5, # Do 5 iterations
           comptype='P', # P=Point source, G=Gaussian, D=Disk
           sourcepar=[2.0,.1,.1], # Source parameters for a point source
           spw='0',  
           outfile='gcal.cl') # Output component list file
