Yes. That's the way I read it. Apologies if "genuine" was ambiguous.
FITLINES seemed to be for background or continuum removal but only along
one axis. Just wondering where to classify it and if there's a better
list of related applications, and most importantly whether or not the
name is misleading. FITVECTORS? There's a FITCONT in Figaro.
