Long story, but can we add the following references to (the bottom of) http://geohazards.usgs.gov/deaggint/2008/documentation.php#gmpe?

Lin, T. and Baker, J.W. (2011). "Probabilistic seismic hazard deaggregation of Ground Motion Prediction Models." Proceedings, 5th International Conference on Earthquake Geotechnical Engineering (5 ICEGE), Santiago, Chile. 12 pp.
