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.

Fig. 1
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.
