your x and y vector lengths for a circular area light

Is that length input the radius or diameter? lookin at this partial eclipse I am
thinking I have no idea.

another way to put it,

using diameter of the sun for vector length, the shadow appears about 2+ times
the size of the moon. is that about right?

hmmm.. more research ... needed
