Does there happen to be (even WIP) code lying around for a bispectrum estimator?
Thanks - this looks like it integrates nicely - I will try it out!
Tangentially related - [this paper](https://arxiv.org/pdf/1906.06831.pdf) argues that CLASS and CAMB are both wrong in the baryon EoMs (and that MB is not consistent with itself between eqn 30 and 67)....
And coming back to the original question, the sound speed term is just dropped in Dodelson because he reuses the cdm eqns (in which the first moment of boltzmann has...
I added a spline for this to IonizationHistory in #44, cs2b(x) seems to match roughly with CLASS at intermediate times (1st attached), but something is happening at high redshift, and...
Both of these issues are qualitatively fixed in 43954ae - the high and low redshift disagreement in csb^2 was due to the previous expression (which I got out of MB)...
Also #53
Added some tests for forward diff applied to background and ionization history in cc2c9d9
Also add C_L ad Pk tests to test suite vs CLASS/CAMB
Plot for this in #44
