AUTOBK is not (substantively) different from ifeffit in that ifeffit
implements the same algorithm. Therefore anything Shelly said in
reference to Athena is relevant to a question about AUTOBK.
"emax" in AUTOBK is the upper end of the spline range in Athena.
Similarly, everything Shelly said about moving between Athena and
Artemis has its equivalent in the old autobk and feffit. In
particular, the business about corefining the background spline can be
done in the old feffit by setting the "bkg" keyword to "true".
