The FeynCalc Manual has the following note about the OneLoop function:
NOTICE: While OneLoop is restricted to 't Hooft Feynman....
In what sense ithe OneLoop resticted to the t'Hooft gauge _GaugeXi->1? Does it also work in the physical gauge _GaugeXi->0? Could you give an example in general gauge that OneLoop cannot handle?
