    Should we use the heliocentric redshifts from the Hamuy paper (this is
    what we used in P99), or from NED?

    It won't make any difference to the cosmology (differences are tiny),
    but might affect the chisquare a bit.

    Does anybody have a strong opinion on this? I suspect the NED ones are
    probably "usually" better, but they are from a heterogenous set of
    references and as such I'm a little nervous just using them.
