[MITgcm-support] changes in calc_diffusivity

Hello

I'm a bit behind the times and am trying to understand changes made
to calc_diffusivity.F (in ver 1.19 or so). Prior to that, KappaRT/S
and ConvectCount were set to ivdc_kappa in calc_ivdc.F:
   KappaRT(i,j,k) = ivdc_kappa

Now, this seems to be done in calc_diffusivity, with the line:
  KappaRT(i,j,k) = IVDConvCount(i,j,k,bi,bj)*ivdc_kappa
My question is, has the definition of ivdc_kappa changed after ver 1.19?
If not, where is the equivalent of the above line of code prior to ver
1.19. Or am I, as usual, completely confused!

Thanks, Samar
