The issue was confusion betweeen classic det-frame/source-frame masses conversion. Basically, the redshift shouldn't have been used anywhere except while extracting the eccentricity at a specified frequency. To reiterate, the general algorithm is: Use the source frame quantities (initial separation, initial eccentricity, masses) to get the e vs f curve. Interpolate this curve. If you want to extract e at fixed (det frame) f22, evaluate the interpolant at f22 * (1 + redshift) f instead you want e at fixed M * f22, then evaluate the interpolant at M_times_f22 / Mtot_src Thanks to Isobel for pointing this out!
