How to use non-linear correction under WsxM

NANOTEC TECHNICAL NOTE 6 V1.0 64. Press onto Assign Pairs and the program will suggest a set ofrelations between real net points and ideal net points. Someof these assignments could be wrong, like shown in Figure 4.Take a look to find these wrong assignments and eliminatethem using the Eliminate pair and clicking on the wrongpoint (not in the circle).Figure 45. If you want to add any other pairs or those that youremoved, add them by pressing the Manual Assign andselecting the point and the corresponding circle.6. Click on Non Linear fit and you will have the non-linearcoefficients for that image. You can verify the quality of theadjustment by pushing then Apply button. You will see thecorrected net in the image on your right. Save thecoefficients in a file by pressing Save and typing the namefor the piezo. Each piezo name can allow up to threee setsof coefficients, with different parameters.7. Repeat the process with the second centers map and save itwith the same name. When asked for overwritting the piezo
