Abstract

Upper and lower boundary fitting of data through least squares

Nicolas Cardiel (Universidad Complutense de Madrid)

Sometimes, given a set of data points, one often wants to determine the upper or the lower boundary to that data set. An automatic and fast approach is to actually fit the data using a modified Least Squares method, where the figure-of-merit function is defined to handle, asymmetrically, the data at both sides of the boundary. Some examples of pseudo-continuum determination of stellar spectra are presented.
