of 2*2 sum-aggregated PAN band       and of LIDAR DTM
is now more securely implemented in 4SM


Using the Panchromatic band for water column correction
to derive water depth and spectral bottom signature:

Landsat 8 OLIP bandset used for this work

Purple_1Blue_2Green_3PAN_4Red_5NIR_6 and SWIR1_7
see response curves


Blue: mask 3        Yellow: mask_4        Green: mask_5        Purple: mask_6
Glint regressions are OK,
including for the PAN band_4 which is now well co-registered

There is hardly any sea-surface clutter; deglinting removes the variations in path radiance

Blue: mask 3     
  Yellow: mask_4
