#     ms   = photographic magnitude of brightest stars involved
#     r    = distance in units of 106 parsecs.
#            The first two are Shapley's values.
#     v    = measured velocities in km./sec.
#            N. G. C. 6822, 221, 224 and 5457 are recent determinations
#            by Humason.
#     mt   = Holetschek's visual magnitude as corrected by Hopmann.
#            The first three objects were not measured by Holetschek,
#            and the values of mt represent estimates by the author
#            based upon such data as are available.
#     Mt   = total visual absolute magnitude computed from mt and r.
