The computed index for negative elevations was off by one. When the
elevation is -45 deg, the selected response corresponded to the entry
for 90 deg, not 315 deg, so sources below the horizon collapsed onto
the overhead response.
To simplify things, we use a short table to map the (positive) elevation
angle to its index in the concatenated database.
