Maximum Corneal Curvature Location Attribute

TypeRequired (1)
Value Multiplicity2
Value RepresentationSingle (FL)

Location of the corneal maximum curvature.

Given as column\row. Column is the horizontal offset and row is the vertical offset.

Image relative position specified with sub-pixel resolution such that the origin at the Top Left Hand Corner (TLHC) of the TLHC pixel is 0.0\0.0, the Bottom Right Hand Corner (BRHC) of the TLHC pixel is 1.0\1.0, and the BRHC of the BRHC pixel is Columns\Rows (see Figure C.10.5-1). The values must be within the range 0\0 to Columns\Rows.
