recfast improvements #85

Closed xzackli closed 1 year ago

xzackli commented 1 year ago

This implements a RECFAST that takes 1 ms, as it should. It also makes improvements to reionization. Instead of having some intermediary arrays for storing the ionization history, it keeps each of the different ODEs that RECFAST solves for different redshift ranges in a structure,

struct RECFASTHistory{T, R, HES, HS}
    đť•Ł::R
    zinitial::T
    zfinal::T
    z_He_evo_start::T
    z_H_He_evo_start::T
    sol_He::HES
    sol_H_He::HS
end

download

Similarly a reionization history is kept like

struct TanhReionizationHistory{T, IH, TS}
    zre_ini::T
    ionization_history::IH
    sol_reionization_Tmat::TS
end
