Hi,

I want to calculate reduced chi square for some cosmological model using Planck TT and low l 2015 data.

Can anyone tell me what should be the no. of data points for that?

Thanks and regards,
Archita

You could just count the number C_L multipoles used. However the log likelihoods are not all normalized in a way that makes calculating a directly comparable chi2 possible (the lowTEB likelihood is not based on C_L).

Thanks Antony!
