Lifan, what do you mean? What sort of s(t) do you imagine? I'm left with
the stupid picture of a lightcurve with a discontinuity at the transition
to the nebular phase. I could even think about implementing it, but, as
Rob says, not for this paper.
In addition to the 56Co problem, there's the question of whether late
supernovae follow the same template, the question of how good our template
is out thar, and questions about galaxy/background subtractions by the
(non-SCP) people that reduced the data. My impression in looking at the
Hamuy data a long time ago is that late times have all sorts of problems,
maybe physics and maybe data reduction.
What do you suggest?
Don
