This package is an add-on to the EGRET package that performs the WRTDS analysis. The WRTDS modeling method was initially introduced and discussed in Hirsch et al. (2010) , and expanded in Hirsch and De Cicco (2015) . The paper describing the uncertainty and confidence interval calculations is Hirsch et al. (2015) .
