Thanks for the clarification, Jonathan. Now I see why I had trouble understanding a few of the entries in the CF standard names table. If I treat them as coordinate variables instead of measured quantities, they make sense.

In this case, the other point is the place where the measurement applies, so the distance from the sun is a coordinate for the geophysical quantity, like e.g. height_above_reference_ellipsoid or projection_x_coordinate, which are also standard names for coordinates in units of distance. We could use the same coordinate name for any quantity one might measure in space as a function of distance from the sun, not just the irradiance, and not necessarily at the location of the Earth or any other body.
