Notes

  • Brene.p6.dat has only 11 samples while Breneman (1987) has 12 results.

  • The illuminance in \(Lux\) for Breneman (1987) datasets given by Luo and Rhodes (1999) is in domain [50, 3870] while Breneman (1987) reports luminance in \(cd/m^2\) in domain [15, 11100], i.e. [47, 34871.69] in \(Lux\). The metadata has been corrected accordingly.

  • The illuminance values, i.e. 14 and 40, for McCann, McKee and Taylor (1976) datasets given by Luo and Rhodes (1999) were not found in [MMT76]. The values in use are the average of both.
