Hi Ryan, I suspect that horizon is supposed to be a list with 360 entries, each being a value in degrees that represents the angle to the horizon. In the middle of an open field, this would be a list of 360 zeroes. If you were surrounded by buildings, it might be a range numbers between, say 20.0 and 70.0, depending on the exact location of the buildings. If you were in the bottom a well, it would be a list of 89's. I would recommend making your own copy of simulate_span() and rip out the horizon part. Then, if you need to account for a varying horizon, add it back in. (Then, send a patch with your improved code!)
