For 60 years ref and 60 years experiment with core2 I get at this position:

 --> compute vprofile:
     --> compute: Kv

problem is here you define a reference run which means that he computes the anomalous Kv, which has of course also negative values. Than you try to scale anomalous positive and negative values with a log10 scaling which doesnt accept negative inputs. I try now to switch from log10 to slog10 scaling when it encounters negativ values together with do_rescale='log10'

hopefully fixed with push https://github.com/FESOM/tripyview/pull/143
