212 PMAC On-Line Command Specification

entering (c+1) columns. If there is any possibility that you may go beyond an edge of the

table, matching entries of Column 0 and Column c should have the same value to prevent

a discontinuity in the correction. Column c in the table may simply be an added column

beyond your real range of concern used just to prevent possible discontinuities at the

edges of your real range of concern.

• Because the outside rows and outside columns must match each other to prevent edge

discontinuities, the three explicitly entered corner corrections must be zero to match the

implicit zero correction at the first corner of the table.
