Wait a minute
Let's return to
-cWL/0.500/0.500/0.500/0.500
-dLsw000.0/000.0/000.0/000.0

and inspect the case of WL_green again

The choice is ours

As of Sept 21rst 2011,
this new strategy of the 4SM calibration process
seems to solve quite some intriguing conflicts,
while getting closer to an acceptable operational solution

Only more seatruth on more images and sensors
will lead us to an acceptable solution
I tend to favour this second solution to the problem,
as it does not imply unpalatable compromises

The problem only with this second solution
is that the calibration diagram looks odd

	This new strategy is applied to an image which does not meet 4SM's assumptions mostly has fairly dark vegetation over most of the shallow bottoms, apart very limited patches of bright sands might have more turbid waters inside the bay due to anthropogenic effects is quite low light in the green band has bad Landsat striping does not have any "glint" for us to remove has very few bright beach pixels

Looks like we'got yet another solution,
although K_red~=0.528 m^-1 at WL_red~=620 nm
is unpalatable for a TM3 band
