LAI output shows little phenology

[NPounder]

Latest version gives LAI with very dampened phenology compared to results a month(is ago)
Run over 10 by 10 chip over rice in Spain.
Now:

December:

The structure is the same but the amplitude has changed.
Have we changed the prior between these?

In both of these the Hessian correction is turned off. In the new version turning it on doesn't change the result.

Looking at x_analysis after the first band (visible) has been retrieved it looks like rsoil nir has been allowed to vary in addition to the visible parameters. ssa and asym for nir do remain fixed at the prior values...

Check H_matrix for band 0 and band 1, they should only have non-zero values for VIS (... NIR) parameters and LAI

The H_matrix is fine. I'll keep looking but it'll have to wait until tomorrow now.

Thinking about, alpha_NIR should be updated as the prior correlation will pull it up. So, actually it is expected behaviour.
