You are right about Convtave**.data file.
When time-averaged it can take intermediate value between 0 & 1.

In offline, the value in Convtave file is multiplied by ivdc_kappa
and added to the background vertical diffusion. But no effect on
vertical viscosity (like ivdc_kappa in a usual on-line run).
