method. As seen from the table, the central wavelengths by the two methods

are very close, but the bandwidth by the moment method is lower than the

conventional FWHM method by about 5% to 13%. It is suggested the moment

method be adopted by all the sensor manufacturers so that intercomparison

is meaningful.

Another spectral parameter that is of concern but often not seriously con-

sidered is the out-of-band response. This is particularly important when

a narrow bandwidth is used for spectral selection as in the case of ocean

color monitoring sensors such as SeaWifs and OCM. In the case of SeaWifs

at the da ...
