* Magnitudes Graph

        m1 =  7.5 + 5 log d + 18.5 log r  [  , 0]  (             - 1984 Jan.  8)
        m1 = 16   + 5 log d - 60   log r  [ 0,50]  (1984 Jan.  8 - 1984 Feb. 27)
        m1 =  4.2 + 5 log d + 18.5 log r  [50,  ]  (1984 Feb. 27 -             )

        * Gray curve is:  m1 = 7.5 + 5 log d + 18.5 log r
