A difference of 0.09 between these two sources is not very large.
There are "p" magnitudes and "p" magnitudes! Not all magnitudes
labeled as "p" magnitudes were measured with the same emulsion and
there are certainly zero-point differences between them. Photographic
mmagnitudes may have better errors in their mean values than visual
magnitudes, but they also have zero-point and scale-difference
propblems.
Best,
Thom
