Honeybee Radiation Analysis - 12h on the hottest day

Hi, I’m new to GH and HB, LB. I used the HB def for calculating radiation on the ground around mirror sculpture in 12 hours period of time on one of the hottest days in the year in the chosen location. The only thing that’s bothering me is that there is no north input. How exactly does it work without north coordinates?

I know I can change from Grid-based Simulation to Annual Daylight but then of course I can’t choose the time period anymore.

Thank you in advance :purple_heart: :raised_hands:t3: :zap:
