Below is an example of IFU observation of a telluric standard star:
UVB arm
VIS arm
NIR arm
Figure 5: IFU telluric standard star (B-type star). One can note the three slices in each order
of each arm. The telluric absorption lines are easily visible in the VIS and NIR arms.
One can also note the effect of the atmospheric dispersion (change of distance between the
slices between blue and red orders in UVB/VIS arms).
