I have finished cleaning up the Equivalent Width paper I gave yesterday at the Spectroscopy-Photometry meeting at my home-observatory in Dewey, Arizona. It is at http://users.commspeed.net/stanlep/EquivalentWidth.doc It is a WORD document and 1.7MB in size. The procedure I came up with is too obvious and simple for someone else to not have thought of it. As a result, I am certain I am probably re-inventing the wheel, so to speak. In any event, this is the paper of my creation I gave yesterday. I understand determining the continuum is central to computing an EW. This is my approach.
