XGENLINE

This software allows the user to calculate the best fit low degree (1, 2, 3 or 4) polynomial calibration function to a set of (X, Y) measurement data, taking uncertainties and covariances associated with the data into account. Then, given measured Y-values and their associated uncertainties, the calibration function can be used to obtain estimates of the corresponding X-values and their associated uncertainties.

The uncertainty structures that can be accounted for are:

  • Uncertainties are associated with the measured Y-values only.
  • Uncertainties are associated with both the measured X- and Y-values and all covariances associated with the data are zero.
  • Uncertainties are associated with both the measured X- and Y-values and there are covariances associated with pairs of corresponding measured X- and Y-values.

The software was developed in MATLAB and compiled into a standalone Windows executable and is downloaded as a zip file. Please start by reading the file readme.txt within that zip file.
