Fitting the WDM mass and the Hydrogen photoionization and photoheating separately:

At \(z=4.2\)

At \(z=4.6\)

At \(z=5.0\)

Joint fit to the 3 Redshift bins

Temperature of the IGM for the fits

Fitting to Boera \(P(k)\) Corrected for resolution effects

At \(z=4.2\)

At \(z=4.6\)

At \(z=5.0\)

Joint fit to the 3 Redshift bins

Temperature of the IGM for the fits
