DCM depth indicator

[acapet]

Hi !

I have an issue with the indicator DCM depth.

According to the dedicated wiki page (and to the .xml files I'm using), the python formula appears as :

([MODEL_DEF])[:,152:192].mean(axis=0).argmax(axis=0)

where MODEL_DEF is your Tot Chl variable.

1. This doesn't provide the depth, but the index of the depth.
2. I'd rather move the time average.
3. And in fact, I'd also get rid of the restriction on the possible depth range..

Only 1 is strictly essential for the relevance of 3.2, since depth-index relationship is non-linear.

I therefore propose something like :

h[0,([MODEL_DEF])[:,:].argmax(axis=1)]].mean(axis=0) 

ie. assuming h changes with time are minor. Else, something like

[ h[t,i] for t,i in zip(time, [MODEL_DEF])[:,:].argmax(axis=1)].mean(axis=0)

if this is tractable within the parsac environment.

It could be that this error is only in my .xml files, but supposedly those are originated from common sources.
