Normalised Hα luminosities as a function of projected rotational velocities (v sin i) for CARMENES GTO sample with N_obs > 25. Stars in the CRX-slope sample are shown by diamond shaped point which are open for Hα inactive stars and filled for Hα active stars. The CRX-slope sample stars are coloured based on CRX-gradient (left panel) and CRX-length (right panel). The stars are labelled according to the same indications as in Table A.1.
