Collecting BPL pixels for optical calibration
requires quite a lot of masking of alien pixels
in this image



Water type is ~OII of Jerlov
Calibration assumes that the brightest pixels are over brightest bottoms.
Because very bright bottoms are so scarce in this image,
the optical calibration is quite unsecure.
BiDim histograms only show shallow pixels.

Kpan  is very high at very shallow depth, 
and increases markedly as depth increases
