You can try to reduce a bit nlive (you’ll have a bit less precise results, but not significantly as far as you don’t lower drastically the value of nlive; of course check anyway the final results and compare them with previously obtained / known results to see if there is something strange) as well as to reduce the range of the parameters, for those you already have some ideas on where it is likely to be the best value (this could compensate the lowering of nlive)

In Tutorial 3.1, the expression of the likelihood in the text does not match the one in the code. I think the correct one is in the code, am I right?

Hi @FrancescoV , the correct formula is that in the text, a parenthesis is missed in the code: actually this doesn’t change significantly the results (it’s only a constant term) but we’ll fix it. Thank you for pointing that out

@abdyoyo If you just want to run bilby.sampler faster, you can lower the nlive and nact values, and increase dlogz. But that might not give you a reliable result.
