Central Obsruction
#1
For reflecting telescope setup, is the secondary mirror percent obstruction defined based on linear units, (e.g. diameter2/diameter1) or area units (e.g. area2/area1).  I think most often the obstruction is reported based on linear units, but not necessarily always, so I wanted to confirm what SkyTools expects.  Thanks!
