Distribution of planetary luminosities in the cold-nominal population at six moments in time as indicated in the panels. Planets with a> 0.11 AU are included. The red solid line shows the total luminosity that contains the internal L_int and (during formation) shock luminosity L_shock. The green long-dashed line is the shock luminosity separately, while the blue dotted line is the deuterium burning luminosity L_D alone. It is only shown if L_D/L> 0.01.
