* Magnitudes Graph

        m1 =  8.2 + 5 log d +  9.3 log r  [   ,-19]  (             - 1988 Aug. 29)
        m1 =  6.0 + 5 log d -  3   log r  [-19,  0]  (1988 Aug. 29 - 1988 Sept.17)
        m1 =  8.5 + 5 log d +  0   log r  [  0, 10]  (1988 Sept.17 - 1988 Sept.27)
        m1 = 19   + 5 log d + 27   log r  [ 10,   ]  (1988 Sept.27 -             )

        * Gray curve is:  m1 = 8.2 + 5 log d + 9.3 log r
