[Question]About coeval and advanced step-by-step brightness temperature plots and data

[1222qs]

After I get the brightness temperature map on coeval, I can call the data of the brightness temperature map, and then I can easily call the get_power function to calculate the power spectrum. However, the disadvantage is that coeval does not consider the spin temperature. Simply enabling fluct seems to have no effect, but when I When obtaining the brightness temperature map from the advanced step, I cannot call its data to calculate the power spectrum. The advanced step allows me to calculate the correct brightness temperature with spin temperature evolution. This is what I want, unfortunately The thing is I can't seem to calculate the power spectrum

Hi @1222qs -- I don't think I quite understand your question. Is your aim to calculate the power spectrum of Ts_box? To do that, you can simply use get_power on spin_temp.Ts_box. If you have a Coeval object, then you can access the Ts_box from that too.

Thank you very much, now i solved the problem and got the correct power spectrum
