Use TauVertexFinder to find ROI based vertex for HLT tau using the the recently introduced "HLT_IDVertex_Tau" vertex container, which is passed explicitly in the "executeVertexFinder" function. Vertex position is also added in the online monitoring (see examples below).
Note:
TauVertexFinder for HLT taus is NOT using TJVA
changes in TauVertexFinder to bypass retrieving on track selection tool and track-to-vertex association in case of no TJVA
Monitor plots example from online monitoring ( for vertex->Z() plot the Xaxis label is actually z vertex position and not "NROis" -> corrected in the MR):
