Notes. Next to the parameter, we show the prior type used and the range for a flat prior or mean and standard deviation when a Gaussian prior was used. In the top part of the table, cosmological parameters are stated followed by the intrinsic alignment and Planck absolute calibration parameter, three baryonic parameters, and two free parameters characterising the decaying dark matter.
