The only change to the instrument description is that the wavelength
ranges covered by the individual detectors have been updated (especially
LW4, that was not used before launch, now is used again). The
ranges of the detectors are indicated in Figure 1, as the
vertical bars. The horizontal bars at the bottom of this figure show the
scan ranges for each of the ten detectors, when using the two most extreme
cases (84 
m on detector LW1 and 178 m) on detector LW4. This then
roughly corresponds to the extended range of operations.
