image.commonbeam - Function
1.1.1 Determine a beam to which all beams in an image can be convolved.
Description
Determine a beam to which all beams in an image can be convolved. If the
image does not have a beam, an exception will be thrown. If the image has a
single beam, that beam will be returned. If the image has multiple beams, this
will be the beam with the largest area in the image beam set if all the other
beams can be convolved to that beam. If not, this is guaranteed to be the
minimum area beam to which all beams in the set can be convolved if all but
one of the beams in the set can be convolved to the beam in the set with the
largest area. Otherwise, the returned beam may or may not be the smallest
possible beam to which all the beams in the set can be convolved.

Example
ia.open("mymultibeamimage.im")
cb = ia.commonbeam()
# convolve all the planes in the image with that beam
ia.convolve2d(outfile="myconvolvedimage.im", major=cb["major], minor=cb["minor"], pa=cb["pa"], targetres=True)
