This module gives a likelihood of the combination d_m / r_s from the DES Y6 data.
It interpolates the ratio of that combination to a fiducial value, and then interpolates
into a pre-computed chi2 as a function of that ratio.



Assumptions
-----------

 - BAO chi2
 - FLRW metric and standard BAO size
