BAO_DM_H covariance replaced with linearized transform of Alam et al. (2016/2017) Table 8 reduced covariance.
Source values taken from ar5iv html lines 456-466 for Table 8.
Transform:
- Inputs: D_M * (r_d,fid/r_d) [Mpc] and H * (r_d/r_d,fid) [km/s/Mpc] at z=0.38,0.51,0.61
- Outputs used by harness: D_M/r_d,fid and D_H/r_d,fid where D_H/r_d,fid = c/(H_scaled * r_d,fid)
- Covariance propagated via Jacobian at the Table 8 mean values (first-order).
Result check (with current theory vector): chi2/6 = 0.501976
