RotatingSymmetry180 and the ReflectionSymmetry thorns define a tensor alias "weylscalars_real", but the symmetries given there do not correspond to those of the usual re[psi0], im[psi0], re[psi1], im[psi1], etc scalars.

The Weyl symmetries as provided in RotatingSymmetry180

static int const weylparities[10][3] = {{+1,+1,+1}, {-1,-1,-1}, {+1,+1,+1}, {-1,-1,-1}, {+1,+1,+1}, {-1,-1,-1}, {+1,+1,+1}, {-1,-1,-1}, {+1,+1,+1}, {-1,-1,-1}};

The symmetries for rpsi0, ipsi0, rpsi1, ipsi1, ..., rpsi4, ipsi4

static int const weylparities[10][3] = {{+1,+1,+1}, / rpsi0 / {-1,-1,-1}, / ipsi0 / {+1,+1,-1}, / rpsi1 / {-1,-1,+1}, / ipsi1 / {+1,+1,+1}, / rpsi2 / {-1,-1,-1}, / ipsi2 / {+1,+1,-1}, / rpsi3 / {-1,-1,+1}, / ipsi3 / {+1,+1,+1}, / rpsi4 / {-1,-1,-1}}; / ipsi4 /

attached is a diff between the current ET version of the Reflection and RotatingSymmetry180 thorns and the "corrected" version.

    closed as duplicate (according to the reporter). It looks like symmetries still are not correct in RotatingSymmetry180 and ReflectionSymmetry
