TABLE 6: 
The effects of simulated, full spectral band shifts on the apparent 
reflectance in the reflective MODIS-N bands imaging water. The 
spectral band shift was applied to forward 5S runs. All spectral 
shifts were toward shorter wavelengths. The results are presented in 
decreasing order of % difference due to a -10 nm shift.
