Detailed Description

The linear transfromation of selected data axis.

It has two coefficients to transfrom axis values like:

scale[naxis] = CoefK * scale[naxis] + CoefB

After linear transformation object is constructed, the coefficients can be defined by three ways:

SetCalibration() - just setting these coefficients;

SetCalibrationByRange() - coefficients defines from range and number of points in this range;

SetCalibrationByPoints() - coefficients calculates from coordinates of two points, where first coordinate is channel number and second - axis value.
