COB-200: fix computation of file.nrParts for beamFormer Piplines
The computation of file.nrParts
(Parset.cc) was based on the nr of subbands in the global SAP (ObservationSettings::SAP
). For LMM pipelines the nr subbands might differ per pipeline. Therfore the nrParts
computation should be based on the nr of subbands in the ObservationSettings::beamFormer::SAP
instead.
This change can be (and is) validated with tMultiPartTABOutput
and tManyPartTABOutput
.
