In MR-K and HR-K the actual covered range depends on the choosen exposure time, DIT. In P82 without FINITO only DIT=25, 50ms and 100ms are allowed, were 50ms (100ms) on the ATs) DIT should only be used in Differential Phase observations, under excellent seeing conditions, or in HR-K mode to have a suitable wavelength coverage. The values in the table are given with starting and ending wavelength (λ) in microns. Note that the covered wavelength range with 100ms is twice the one with 50ms.
