#2282: gallery examples use low-order integration n Multipole

 Reporter: Roland Haas
   Status: new
Milestone: 
  Version: 
     Type: enhancement
 Priority: minor
Component: EinsteinToolkit website

Comment (by Erik Schnetter):

The `DriscollHealy2D` rule is the best rule we implemented. It has spectral accuracy.

The so-called `midpoint` rule doesn’t implement the midpoint rule and is only 1st order accurate, different from the documentation.

Most integration methods neglect the fact that the domain is periodic in the phi direction and introduce unnecessary errors there.
