Visual SAT-Flare Tracker 3D

TWILIGHT SETTINGS - WINDOW  

Some program functions may distinguish between day-time and night-time to produce results. In that case, the Sun elevation is used to choose the right behaviour. By means of this window the user can specify the minimum Sun elevation above the local horizon that has to be met in order to consider day-time.

The Sun elevation has to be entered in decimal degrees. As an example, if the user wants to define night-time when the Sun is at least 5 degrees under the local horizon, the value -5 has to be entered.
