I just reviewed the ASK 2014 paper (from ​http://peer.berkeley.edu/publications/peer_reports/reports_2013/webPEER-2013-04-Abrahamson-Silva-Kamai.pdf) and it doesn't mention treatment for line sources. The relevant equations are in section 4.4, pages 28-30. Specifically, it's the T3 distance taper in the hanging wall model.

Peter, do you have a suggestion for how to deal with this issue? Or should we contact the authors?
