LL scatter in the V-band (green) and W_H magnitudes (pink), for Z = 0.014 (left), 0.006 (middle), and 0.002 (right panel). The histograms show the difference in magnitude between the individual SYCLIST IS stars and that of the SYCLIST LL fit at the same log P. The shaded regions correspond to the standard deviation, hence to the scatter of the LL and the values are reported on the plot with the corresponding colour.
