Any idea of what is all the green on this photo? It says it is the symmetry (GCAL report). I wonder if this is the same as ASET? If so I thought that only red was sign a sign of good light reflection?
It is reflection of light that enters the sides of the diamond. (close to the horizon)
That light gets tinted green by that lower part of the ASET scope.
The light map for the gcal scope is not open and public and not the same as ASET.
The colors do not mean the same thing and it can not be used the same way as ASET to judge light performance.
