Selection Function Normalization for HI Intensity Mapping #444

Open ramanujakothari opened 2 years ago

ramanujakothari commented 2 years ago

Dear Developers,

I'm Rahul Kothari, a postdoc at UWC, South Africa. First of all, I thank you very much for developing such a useful code. I wish to ask you a question related to the selection function normalization in the context of HI Intensity mapping.

Specifically, I wish to normalize the selection function wrt to mean HI temperature \bar{T}(z) = .056 + 0.232z−0.024z^2 mK

i.e., to make int \bar{T}(z) W(z,z_i) A dz = 1 where A is some constant and W is the tophat window function.

I would highly appreciate any help in this regard.
