#1759: need tensorparity=-1 for WeylScal4::curvIi_group and curvJi_group ------------------------------------+--------------------------------------- Reporter: physicsbeany@… | Owner: Bernard Kelly Type: defect | Status: new Priority: minor | Milestone: ET_2014_11 Component: EinsteinToolkit thorn | Version: development version Keywords: weylscal4, parity | ------------------------------------+--------------------------------------- The WeylScal4 gridfunctions curvIi and curvJi are pesudoscalars with the same parity properties as Psi2r and Psi2i. However, they're currently assigned no tensorparity attribute, so they're treated as scalars.
As a result, for a z-aligned Kerr BH (EinsteinInitialData/IDAnalyticBH) evolved with reflection symmetry across the x-y plane, an interpolation of curvIi to a coordinate sphere will yield different values for the z<0 points than the same data on a full grid.
Can we set "tensorparity=-1" for both these groups, to fix this issue?
