Calculates the direct beam solar energy received on a horizontal surface between specified
start and end times. Implements Equation 19 from Appelbaum & Flood (1990).
Usage

Arguments
- Ls
Areocentric longitude [deg]
- phi
Planetary latitude [deg]
- tau
Atmospheric optical depth (dimensionless)
- Ts_start
Start of integration period [h]
- Ts_end
End of integration period [h]
Value
Beam insolation over specified time period [Wh/m²]
