Problem with ell_range #8

Closed Eminencetoosure closed 2 years ago

Eminencetoosure commented 2 years ago

Hello alessio, Please i am working on cosmosis, i took some time to understand your cosmosis pipeline and the code itself. but i have a problem with how you generate "ell_range". can you please help me further on understanding the (ell_range = training_features["mode"]). ![Uploading Screenshot 2022-07-24 at 17.10.34.png…]()

if you can explained to me better how you get the tt log_spectral

Hi @Eminencetoosure , the ell_range is the range of multipoles at which you compute your CMB power spectrum, or the Fourier modes at which you compute the matter power spectrum. Note the typo mode --> modes, it should not be ell_range = training_features["mode"], it should be ell_range = training_features["modes"]. The log_spectra are the logarithm of the power spectra computed by the Boltzmann code, which CosmoPower emulates.
