Ramon!

Would you please reply to bernardcleyet@redshift.com attaching a scan of

determine if, as I suspect, the method may invalidate a routine Chi
Square analysis of such treated data.

Hello Tom,

We follow
the standard procedure of
incorporating the uncertainty in x into the uncertainty of y; as
explained in “Data
Reduction and Error Analysis for the Physical Sciences” by Philip
Bevington and D. Keith Robinson. See page 100 of the second edition (a

edition is now available) for a discussion on this topic.

Hello All,
This brings up another question for the group - how do you do data
fitting when
there are uncertainties in both X and Y variables?
