Measuring the fine structure constant on white dwarf surfaces; uncertainties from continuum placement variations
Chung-Chi Lee, John K. Webb, Darren Dougan +2
Searches for variations of fundamental constants require accurate measurement errors. There are several potential sources of errors and quantifying each one accurately is essential…
Addendum: Precision in high resolution absorption line modelling, analytic Voigt derivatives, and optimisation methods
Chung-Chi Lee, John K. Webb, Robert F. Carswell
The parent paper to this Addendum describes the optimisation theory on which VPFIT, a non-linear least-squares program for modelling absorption spectra, is based. In that paper, we…
