Our main advice for using the LineForest equivalent widths is to be aware that it derives equivalent widths from MWM BOSS spectra based on a convolution neural net trained on by-hand equivalent width measurements from ~3500 BOSS spectra spanning a range of target classes from young stellar objects to OB stars to cataclysmic variables. While more traditional techniques were tried, they did not work across a wide range of stellar types.
How well LineForest equivalent widths match those measured from continuum-normalized spectra in the usual manner has not been tested across a wide range of spectral types.
