Could anyone here on this newsgroup help solve this disagreement over what the results of these following calculations will be..
A) Where z=0 and s=1.1 in the formula w=s(1+z), does w = 1.21?
B) Where z=0 and s=1.1 in the formula w=s(1+z), does it follow that s=1.21?
C) In this chi square fitting formula below .... I(t) = Imax * ( fR((t-tmax)/s(1+z)) + b ) where z=0 and s is unknown, is it possible to calculate that s=1.21 just by looking at the formula above ? Or to calculate s does one have to perform the chi squared fitting function?
