    3131after arcetri videocon probably for alignment Argos source is the best solution. I would start also with mirrors in LBTI configuration as the light needs to go to SOUL WFS and would mostly use our internal degrees of freedom (internal of course including the dichroic). Of course some tweaking either of mirrors or SOUL WFS x-y-z is possible. [need to talk. does this mean that we need someone to look into LBTI AO system or support from SOUL Arcetri team?]

    33 LM: absolutely, I would minimize any movement of the telescope's mirror, as that is an already commissioned focal station, so the telescope collimation is already good. We shall use our internal mirror IN-TT and DM to align SHARK-NIR to the telescope. If errors in the mechanics are too big to be only compensated by our mirrors, then we can move the telescope's mirrors. In this case, SOUL shall "chase" the beam using its XYZ linear stages. As far as I know, SHARK-NIR will not be used together with LBTI (in trinocular observations, LMIRcam receives light from DX side), but it is worth, at the end of the alignment, to check that we are not vignetting any of the technical FoV of LBTI (which is 100'' more or less). We also have to align the telescope pupil to our internal pupil, other than the PSF.

I think the latter activity can be performed only at night time...We also have to align the telescope pupil to our internal pupil, other than the PSF.
