Stellar population parameters in the rest-frame UVJ diagram. At different redshift bins, we present the intrinsic colours (m_F551 − J)_int (X-axis) and (m_F365 − m_F551)_int (Y-axis) after correcting for extinction for the mass complete sample of quiescent galaxies (see stellar mass completeness at the top). The different stellar population parameters are colour-coded as a function of their values and obtained using BC03 SSP models (see the colour bars to the right of each row). From top to bottom: stellar mass, extinction, mass-weighted age and metallicity, and specific star formation rate. All the parameters were spatially averaged through a LOESS method. Black crosses illustrate the median uncertainties in both (m_F551 − J)_int and (m_F365 − m_F551)_int intrinsic colours. The dotted black line encloses the rest-frame colour ranges assumed for selecting quiescent galaxies in Moresco et al. (2013, see Eq. (1)), while the dashed line illustrates our colour limit for selecting quiescent galaxies (m_F365 − m_F551)_int >  1.5. We illustrate the colour variations owing to a reddening of A_V = 0.5 (black arrow), assuming the extinction law of Fitzpatrick (1999).
