Figure 5. Overview of the results.

The mean coefficient of temperature (Q) for luminances up to 1 cd m are represented by black squares, and for luminances above 1 cd m, by gray squares. The shaded region correspond to coefficient of 1. Coefficients smaller than 1 were inverted, for sake of comparison. Similarly, the blue squares represent the mean amplitudes of the coefficient of luminance (K) for temperatures up to 22C, whereas red squares represent the mean amplitudes for higher temperatures.
