It's something to do with reionization; if I set `tau=0`, both curves agree.
Perhaps this is physical? Reionization boosting the baryon temperature, which increases the sound speed and hence the baryon Jeans scale. But that would suppress matter clustering at a fixed scale,...
Could be; setting AccuracyBoost=3 causes dverk to return the error "unable to satisfy the error requirement with a particular step-size that is less than or equal to hmin, which may...
Hmm interesting! I guess it's because the matter temperature is going negative.
Is the `k` range right in that plot? It looks much too large an effect on those scales.
I suppose that technically the sound speed equation you had originally is always correct (although it neglects the time evolution of the mean molecular weight, which !=0 during reionization), so...
OK, the plotting looks fine. I was surprised because I was only seeing changes to P(k) at k > 100 h/Mpc, not the k=1 h/Mpc scales you find here. But...
