CosmoCoffee

[Felipe Maldonado]

Hello,
Is there any reason to expect get_cmb_power_spectra to return power spectra with slightly different values each run (same cosmology)?

I've observed a difference of the order of 1E−9 %, which is of course, minuscule, but I'd like to know if this is expected of CAMB or I did something to cause it.

Thank you very much,
Felipe

You can expect small variations from things like random timing variations in the OpenMP threading.

Thank you for the clarification.
