(***) - The values given are B (blue magnitude) values, the outcome will differ according to the method used (photographic/CCD/ visual), and extreme caution should be excercised when applying these values. These are general approximations. Other considerations that might come into play are the time in the evolutionary process that the event is first viewed. (****) - The absolute maximum brightness is taken from a Gaussian fit of Type II SNe at the distance modulus of the Virgo Cluster (M-m=31.7)(7) (also see above). (a) - Calculated as the apparent blue magnitude in the Bt system, and the absolute blue magnitude in the Bt system. Some errors that are cited: apparent magnitudes (~0.2m), galactic absorption corrections (~0.15m), intrinsic absorption corrections (~0.25m), corrected velocities (~[0.1m), and random deviations (~[0.1m)..."Hence the compounded mean error in absolute magnitude is (~[0.4m)" (1) (:) - Values for which no internal absorption correction could be applied,
