RemarksThe field correction is associated with an immutable correction format, which is required to convert correction values from real-world units into the binary format saved in the correction file, and vice versa.
The field correction consists of a grid that divides the entire field into equi-spaced rows and columns. Accessing the correction table is in the order row, column - similar to accessing a mathematical matrix.
Row 0 and column 0 are mapped to the bottom-most row and left-most column, respectively.
