# CoulombVertexSingularVectors

## 1.Brief description

The CoulombVertexSingularVectors object contains the transformation from the auxiliary-field basis to the plane-wave basis $$U_{G}^{F}$$ as input. This transformation matrix needs to be provided by the interfaced electronic structure code and should be read from an external file using the Read algorithm.
