 •       RR is mounted on the SX side. Using RR / ARGOS on-axis calibration light source, M2 and M3 of the LBT are moved to have the on-axis spot on the reference position on SCICAM (also TECCAM), identified during the internal alignment of the instrument. (Do you want to use the IN-TT mirror for the alignment?) Coma, if present, is minimized by looking at the out-of-focus image, shifting and tilting M2, and keeping the spot fixed on SCICAM. Astigmatism, if present, can be reduced by applying the astigmatism terms to the M2 shape. Focus is adjusted shifting M2 along the optical axis. The daytime collimation model is recorded.
 •       Do we need to check if LBTI is getting the light in their detectors? Do we ever run both SHARK-NIR and LBTI parallelly? Maybe it is required for running the LBTI AO system?
+* TBD
 **Success criteria**
 •       On-axis spot from the RR/ARGOS light source at the reference pixel of the SCICAM.
 •       The daytime SHARK-NIR collimation model recorded.
 •       Something with LBTI?
+* TBD
 **Notes**
 •       SCICAM has large persistence. Avoid super-bright stars (LM: this is a daytime activity. I would move this note to P3.6. Secondly, I disagree, at least for the first part of the alignment. In fact, I would need a very very bright light source in order to see the footprint of the beam on the dichroic and IN-TT, to ensure it is fairly centered on the optics. I do not know how bright is ARGOS source as I never used it. if it is not very bright we might ask Tom Herbst if we can use Baby Argos for this phase? Of course for this activity, to preserve detectors we can close the SHARK-NIR shutter). Use TECCAM first, and then SCICAM (with ND filter) later for the alignment.
