Example: The error between X=0 and X=4 is zero, then it ramps up to 0.002 at X=5, hits 0.003 at X=6, then remains at 0.003 for the next 8", until X=13. Then it ramps back down to zero at X=14, and hits -0.001 at X=15, where it stays until X=21. So you would use the following X,Y pairs: 0, 0.000 4, 0.000 5, -0.002 6, -0.003 13, -0.003 14, 0.000 15, 0.001 21, 0.001 You can use up to 16 pairs. Best approach is to plot your measured errors on a piece of paper or in a spreadsheet, then find the set of 16 (or fewer) straight line segments that best matches your measured error plot. -- John Kasunich jmkasun...@fastmail.fm ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
