Hi Chris,
thanks for your document, it is a useful work you have done to clarify
this point. My personal opinion is that adding a 0.05 mag uncertainties to
all the SNe is the easiest way to go, especially since we don't know what
system they have used in Tonry and Riess'papers. Moreover, correcting for
this small amount is not changing the results we present. Anyway, let's
see what the rest of the collaboration would like.
I have one question about the section called "conclusions". You say:
"If we choose not to apply the correction, then a suitable
systematic error for IR-optical colors should be 0.05 magnitudes and
this should be added to the systematic error which is listed in table 8.
If we choose not to apply this correction, then the systematic error
is 0.02 magnitudes."
The second sentence seems to contradict the first one. Am I missing
something?
Cheers
Serena
