Table 2:
Robustness of the full-sky fit of the
calibration H0/H0* and the deceleration parameter q0 at
small redshifts. We compare the number of degrees of
freedom (d.o.f.),
/d.o.f., and the best fit cosmological
parameters for the four data sets described in the text for various
assumptions on
acceptable light extinction
,
peculiar velocity dispersion
,
intrinsic dispersion
,
as well as redshift interval included in the fit. Our analysis with
includes all SNe without information on
,
but we exclude those when investigating
.
