Spatial Model of Sky Brightness Magnitude in Langkawi Island, Malaysia

Research in Astronomy and Astrophysics, 2017
Sky brightness is an essential topic in the field of astronomy, especially for optical astronomical observations that need very clear and dark sky conditions. This study presents the spatial model of sky brightness magnitude in Langkawi Island, Malaysia.

Comparison of Psychophysical Methods for Brightness Scale: Magnitude Estimation and Magnitude Production

Journal of Korea Society of Color Studies, 2022
The psychophysical experimental methods affect the observer???s evaluation because of the bias error. Therefore, it is necessary to design experiments properly. In this study, the experimental methods were compared for the brightness scale experiment, and the effect of stimuli setting was investigated. Magnitude estimation and magnitude production were
