Regarding the second question:
TarcerExpand has an option TarcerReduce which is set to $BasisIntegrals.
$BasisIntegrals is the list of integrals for which TarcerExpand knows
the analytic expressions. This can be extended as needed.
> I am trying to use Tarcer to analyse some two loop self-energy diagrams. I would like to understand the divergent and finite parts of the integrals. At first look it seems like TarcerExpand might do the trick but it seems to have very limited knowledge of basis integrals. I have two questions:
> 1. Is there a reerence for the derivation of the integral expressions that TarcerExpand does understand.
> 2. Can TarcerExpand be extended to include other integrals and if so how?
> Many thanks,
