Camera Target size configuration

[RKElectricalman]

We've been fooling around with the Target.cpp and Target.h files to understand enough of it to see how the code determines the size of the target. After a good hour of reading through, and fact checking, we couldn't really figure out how the values in Target.cpp correspond to the real life values of the target.

Does anyone know how the values of Major radius min and max, and minor radius min and max relate to the actual 38 inch diameter of the real life target?

The question is for understanding AND application, and any help you give us will help us greatly now and in the future.

Thanks!
