TPAR: Tolerance on Parameter Data

TPAR is used to tolerance parameter data. The Int1 number is the surface number. The Int2 number indicates the parameter number. Search the help files for "Surface Types" for tables listing which parameter numbers are used for each surface model. TPAR is useful for determining tolerances on aspheric coefficients, and more. Min and max are the changes in whatever units are used by the parameter.
