Message:

0.5 pixel error in pmPCM fitting; update sersic-like models to use a more-accurate central pixel flux value; update sersic-like models to have consistent Sxx / axes.major relationship (axes.major is effective radius, not sigma); fix flux integration (sersic-like models have an analytical form, other models were not correctly integrating f(r) rdr)
