calc(aver=[], datatopdir='.', lskip_zeros=False, proc=-1, rank=0, rmfzeros=1, rmbzeros=1, iy=None, l_correction=False, t_correction=0.0, dim=None, timereducer=None, trargs=[], tindex=(0, None), imask=None)

object returns time dependent meridional tensors from Averages object aver.z. u, acoef and bcoef and aver.t

For long DNS runs the ‘zaverages.dat’ file can be very large so MPI may be required and the data is loaded by processor as default.

lskip_zeros=True identifies the resetting of the testfield and rmbzeros and rmfzeros number to exclude before and following By default none are removed.

iy is the index array that is computed in this MPI process, which may be a subset of the array on this processor

l_correction=True permits the pencil coefficients computed prior to the Pencil Code correction implemented after time=t_correction to be rescaled accordingly to match the new formulation.

trargs contain optional arguments for the time treatments: mean, smoothing, etc.

tindex is set to limit the range of the iterations loaded from Averages in zaverages.dat

The index imask, excluding the resets, can be specified to ensure all processes use the same mask
