Current Field

The Current Field tab allows you to edit the same parameters found in the columns of the Field Data Editor or in the System Explorer. The parameters are displayed for the currently selected field and represent the X and Y Field values, Field Weight, Vignetting Factors, and Field Comment.

The vignetting factors are defined as VDX, VDY, VCX, VCY, and TAN. These factors represent decenter x, decenter y, compression x, compression y, and the tangential angle. For more information about vignetting, see "Vignetting Factors" under "Conventions and Definitions".
