Thanks Roy. I've tried this. However, the spread of my points covers most of the area involved. So I can't reduce the total area very much, especially when I need to keep a buffer around the points for r.horizon. What I'm looking for is a way to tell GRASS to calculate r.horizon values only for a list of points, rather than an area. And for the second step, to calculate r.sun beam values using the same points.
