Notes. Reduced χ2 values for all model WDLFs
(first column), reduced χ2 values corresponding to the
upper limits (second column), minimum value that the reduced χ2 can
become () by multiplying the model WDLF with
a factor f (third and fourth column). In the first two
columns there are 28 degrees of freedom, in the last column there is one degree of
freedom less.
