Dear Ron,
Thank you for bringing to our attention your excellent and magnificent Celestial Navigation Workbook.
In practice and from your own experience how does your 2nd order regression perform since you seem to be using the (x2) 2nd order coefficient directly derived from the data set and not precomputed from the Observer's (approximate) environment ? (RE: Linear-regression-other-tools-Couëtte-oct-2018-g43055)
In other words, does your 2nd order regression bring a definite practical advantage over the 1st order [linear] one ?
Congratulations again for your superb Celestial Navigation Workbook achievement !
Antoine
