The X-axis is the controlled variable, the Y-axis the dependent. However, (from my understanding which is sketchy), the software controlling the input has a feedback loop and attempts to adjust the rate and spacing of the input to provide good data around the fine detail of the slope; so the input isn't necessarily exactly linear, though if you inspect the output closely, it seems to have a linear step size. Indeed. I suspect that the discontinuities I'm seeing are a result of the control software back-stepping around certain positions to correct for detected 'external influences' (such as eddy current build-up or induction lag). It is this hypothesis that I am going to try to get conformed by the equipment manufacturer. > sgolay filter > (http://en.wikipedia.org/wiki/Savitzky%E2%80%93Golay_filter";>http://en.wikipedia.org/wiki/Savitzky-Golay_filter)otherwise > the loess regression > (http://cran.r-project.org/doc/contrib/Fox-Companion/appendix-nonparametric-regression.pdf) That pdf does not seem to be available to me?

'scuse my ignorance of these things; but it the "CWA scilab module" available as an ATOM? (If so, in which category?)
