Is there a merit function that returns the "GEO radius" from the spot diagram?

I would like to return the geometric (not RMS) spot radius in the merit function editor. I wasn’t able to locate this in the documentation. 

Thanks for any help,

John

I think you can choose PTV instead of RMS, and this should be what you need.

Hello @Andrey.Pravdivtsev ,

Thank you. The GENC operand with energy fraction of 100% is very close to the GEO radius from the spot diagrams.
