  We explore methods of fitting templates to cosmic microwave background (CMB)
data, and in particular demonstrate the application of the total convolver
algorithm as a fast method of performing a search over all possible locations
and orientations of the template relative to the sky. This analysis includes
investigation of issues such as chance alignments and foreground residuals. We
apply these methods to compare Bianchi models of type VII_h to WMAP first year
data and confirm the basic result of our 2005 paper.
