Linear fit (see text for more details) to CALIFA 
data, and comparison with Courteau (1997) and Pizagno et al. (2007) TF fits. Point sizes are proportional to 1 /Vmax weights, colours indicate insufficient spatial coverage of the velocity field (sampling of the rotation curve is lower than 1 ropt). The fit to 
is also shown in the plot.
