[Users] using WeylScal4 and Multipole thorns in McLachlan

[Jose Fiestas Iquira]

Hello,
Please correct me if the way to disable scalar output for complex grid
functions is e.g. deleting the lines WEYLSCAL4::Psi4r and WEYLSCAL4::Psi4i
below.
They are the only I recognize as complex numbers. Which information am I
loosing so?

----------------------------------------------------------
ActiveThorns = "CarpetIOScalar"

IOScalar::one_file_per_group = yes

IOScalar::outScalar_every = 128
IOScalar::outScalar_vars  = "
        CarpetReduce::weight
        ADMBase::metric
        ADMBase::curv
        ADMBase::lapse
        ADMBase::shift
        ADMBase::dtlapse
        ADMBase::dtshift
        WEYLSCAL4::Psi4r
        WEYLSCAL4::Psi4i
        ML_ADMConstraints::ML_Ham
        ML_ADMConstraints::ML_mom
        SphericalSurface::sf_radius
        QuasiLocalMeasures::qlm_newman_penrose
        QuasiLocalMeasures::qlm_weyl_scalars
        QuasiLocalMeasures::qlm_ricci_scalars
        QuasiLocalMeasures::qlm_twometric
        QuasiLocalMeasures::qlm_killing_vector
        QuasiLocalMeasures::qlm_killed_twometric
        QuasiLocalMeasures::qlm_invariant_coordinates
        QuasiLocalMeasures::qlm_3determinant


Thanks,
Jose
