I have corrected footnote (8) in my article (appended below) to give the reference to Oreste Caroppo’s 2005 double-helix photon article which I just discovered a few days ago. I had inserted a note about his article at the end of my article, including the link to his article, but by mistake it didn’t get into the footnotes also. I also added a note about an earlier published double-heliix photon article of mine from 2002 which found the same numerical results describing the double-helix photon as in my present article (and in Carappo's article).</div><div class=""> More later.</div><div class=""> Richard</div><div class=""><br class=""></div><div class=""></div></body></html>
