Q:  What is the apparent magnitude of the peak of the globular
            cluster luminosity function?


               The graph shows    m(V)  =  25.6     approximately




  Q:  Assuming that the absolute magnitude is M(V) = -7.9,
            what is the distance modulus to this galaxy?



                (m - M)  =  25.6  -  (-7.9)  

                         =  33.5


            This yields a distance of 50 Mpc.
            
            The authors adopt a different absolute magnitude for
            the GCLF, M(V) = -7.58, and so derive a somewhat smaller
            distance modulus of 33.1.  Their distance is 42 Mpc.
