  60 +The diffuse response computation for a stacked analysis require the ipix() and iend()
  61 +attributes set in order to properly cache the response values, yet the ctmodel
  62 +modifications introduced in version 1.3.1 did not properly set these attributes.
  63 +This has been corrected (#2171).
