Although one could mitigate the impact on the $f_\textrm{NL}$ signature by adjusting the redshift range or the luminosity threshold of the tracer sample being considered, we suggest that, for future surveys probing large cosmic volumes, relativistic corrections should be forward modelled from the tracer luminosity function including its uncertainties.

The baryonic acoustic feature is used to obtain model independent constraints cz/H/r_s = 12. 28 +- 0. 82 (6. 7 per-cent accuracy) and D_A/r_s = 9. 05 +- 0. 27 (3. 0 per-cent) with a correlation coefficient of -0. 5, where r_s is the sound horizon scale at the end of the baryonic drag era.
