# * CLASS input parameter file *
# *~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*
# This example of input file, intended for CLASS beginners, lists only
# the most common input parameters with small comments. Only lines
# containing an equal sign not preceded by a sharp sign "#" are considered by
# the code, any other line is considered as a comment.
#
# The normal syntax is: parameter = value(s)

# ----> General parameters:

# REQUESTED OUTPUT FROM CLASS (Important!)
# - 'tCl' for temperature Cls,
# - 'pCl' for polarization (TE,BB,EE) Cls,
# - 'lCl' for CMB lensing POTENTIAL Cl (Cl^psi-psi, required for lensed Cls),
# - 'nCl' (or 'dCl') for density number count Cls,
# - 'sCl' for galaxy lensing potential Cls (Cl^phi-phi),
# - 'mPk' for total matter power spectrum P(k),
# - 'dTk' for density transfer functions,
# - 'vTk' for velocity transfer functions,
# - 'Sd' for spectral distortions
# --> deflection d: Cl^dd = l(l+1) C_l^phi-phi
# --> convergence kappa and shear gamma: the share the same harmonic
