Abstract
We derive a general law for the M-2 factor of any beam generated by a parti
ally coherent Schell-model source. The fourth power of M differs from its m
inimum value, attained in the coherent limit, by a term proportional to the
second derivative of the modulus of the spectral degree of coherence evalu
ated for zero argument. Examples are given for cases of practical interest.
