     Average the Polarisations together.
     Parameters:
         scan   - a scantable
-        mask   - an optional mask defining the region, where
-                 the averaging will be applied. The output
-                 will have all specified points masked.
-                 The dimension won't be reduced and
-                 all polarisations will contain the
-                 averaged spectrum.
