Confidence contour and BAO
Hi,
Does anybody know how one obtain the 1 and 2\sigma confidence contours for the parameters of a cosmological model with by using the dimensioneless quantity A get with baryon oscillations? I know how to define the chi^2 and confidence contours with the distance luminosity data of supernovae but I do not see how to proceed with the dimensioneless quantity A of baryon oscillation. Apparently the data consist in the measure of the quantity A=Sqrt(Omega_m)E(z_1)^{-1/3}(1/z_1\int_0^z_1 dz/E(z))^{2/3} in z_1=0.35 with E(z)=H(z)/H0 and H, the Hubble function. How can I define a chi^2 with only this measure? How do I define the confidence contours Thank you for your help Stephane [Mod. note: MIME damage in body fixed.
