#950: "Correct" Weyl Scalar symmetries ---------------------------------+------------------------------------------ Reporter: yosef@… | Type: defect Status: new | Priority: major Milestone: | Component: Other Version: | Keywords: ---------------------------------+------------------------------------------ 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.
