**The data**
Mulroy Bay is located between Sheephaven Bay (west) and Lough Swilly (east)	TCC over the full Landsat scene
co-registration BLUE band LC82070222016153LGN01_B2	co-registration NIR band LC82070222016153LGN01_B5
PAN band LC82070222016153LGN01_B8	PAN-MULTI co-registration : can it be improved in view of PAN sharpening? Origin of the PAN band is offset by +15.0 m in XUTM - 7.5 m in YUTM
Most of the "noise" is actually well correlated sun glint, NOT SO for the PAN band though	NOISE As it collects all photons between 500 and 675 nm, one would expect the PAN band to be much less noisy than narrow bands. NOT SO! WHY? Can this be improved? I wish the response curve would include the 675-850 nm range.

**Deglinting**
Shapefiles for estimating the glint regressions Profile_blue is also shown Backdrop is a TCC of the deglinted data	Glint regressions are quite good, based on the SWIR1 band
Deglinted NIR band excellent over open waters cannot beat the backscatter by suspended solids over inland waters	Deglinted RED band exhibits some striping over open waters waters not quite homogeneous muddy waters of Lough Swilly stand out inter-tidal waters at Lough Foyle stand out
Deglinted PAN band Lough Foyle waters pour out NorthWestwards	Deglinted GREEN band Lough Foyle waters pour out NorthWestwards
Deglinted BLUE band Lough Foyle waters pour out NorthWestwards	Deglinted COASTAL band striping over open waters Lough Foyle waters pour out NorthWestwards
	Radiances along Profile Blue Backscatter is much stronger West of waypoint 2 and East of watypoint 5 Between waypoint 2 and waypoint 5, waters exhibit lowest backscatter Between waypoints 3 and 4, a distinct shoal is not detected in RED band, quite bright in the GREEN band, and much less in both BLUE bands At waypoint 6, one can notice the striping all bands except SWIR1 and NIR Lsw: altogether, estimating deep water radiances for the simplified optical model can seem an un-reasonable challenge therefore, for a conservative standpoint, thresholds should be set a high values

**Calibration**
Calibration diagram 6, 5, 3, 2 for Mulroy Bay Coastal 1 water type Kblue/Kgreen=0.90: this is clearly evidenced in X2,3 vs X5 diagram. Kblue=0.244 m^-1 Kgreen=0.271 m^-1 There is hardly any color separation for the pair Blue vs Green: 4SM modeling is ~impossible	Calibration diagram 6, 5, 4, 2 for Mulroy Bay Coastal 1 water type Exhibits significant color separation for the pair Blue vs PAN therefore 4SM modeling is possible, down to in excess of ~10 m
