Parameters of the best fit with nightfall to the V -band light curve ofCyg OB2 #5.

Parameter	Value
q	3.2 (fixed)
fill_A = fill_B	1.04 ± 0.03
i_A+B (°)
T_A (K)	36 000 (fixed)
T_B (K)	25 000 ± 500
(l_C + l_D)∕(l_A + l_B + l_C + l_D)
Spot latitude (°)	0 (fixed)
Spot longitude (°)	1.7 ± 0.5
Spot radius (°)	36.8 ± 1.0
Dim factor	1.9 ± 0.1

Notes. The uncertainties on T_B, the spot radius and dim factor are only indicative as these parameters present a high degree of correlation.
