Hi,
I'm a new user of RayMan and I have few basic questions I need to resolve. If we input a fish eye image does the Cloud cover option in GUI gets calculated automatically?
My second question is do we only need one input from either fish eye images, topography or obstacles?

And third, I'm going to do a research on calculation of PET values for urban parks in my country but I don't know whether RayMan or SkyHelios will be better suited? I know RayMan has no wind model, but will that make a huge impact on my results if I use RayMan. Can you please differentiate between the two models?
Thank you
