Hello,
I’m trying to recreate Fig. 3 from your Rayleigh paper https://arxiv.org/pdf/1307.8148.pdf. I’ve cloned and compiled the CAMB rayleigh branch, and changed only three things in the supplied params_rayleigh.ini file:
output_root=output/run1
get_scalar_cls=T
get_tensor_cls=F
Running this, I find an extra feature in the Rayleigh-primary cross spectrum at l=183 for 143 GHz that doesn’t match your figure (see image at link below). The feature decreases in depth by an order of magnitude if I set accuracy_boost=2, but does not change upon further increasing the accuracy. Any idea what could be causing this?

Not sure, the signal is very small - you many need to increase the other accuracy parameters (L sample boost).
