    22•       **Phase**               :       3 
    33•       **Status**              :       Draft   
    44•       **Category**            :       Nighttime testing (functionality and operability) (C4)
    55•       **Recurrence**  :       once at commissioning
    6 •       **Duration**            :       1 hour(s)
     6•       **Duration**            :       1 hour
    77**Description**
    8 •       Verify the acquisition sequence for SHARK-NIR
     8•       Adjust the orientation of the coronagraphic masks with respect to the true orientation of M2 spider.
    99**Prerequisites**
    10 •       Atmospheric conditions: should be able to see bight stars on sky (preferably close to zenith?).
     10•       Atmospheric conditions: should be able to see bight stars on the sky (preferably close to zenith?).
    1111•       Authorize SHARK-NIR on the SX side.
    12 •       Suitable bright enough target (including the possibility of performing AO).
     12•       Suitable bright enough star close to zenith to have negligible effects from flexures (including the possibility of performing AO).
    1313**Procedure**
    14 •       Start the acquisition sequence: collimating the telescope to reduce the aberrations, close the loop and produce better ASM flat, NCPA estimation using phase-diversity algorithm, close SHARK-NIR tip-tilt+NCPA loop, and check the PSF quality at SCICAM.
    15 •       Save telemetry (open and closed loop of the ALPAO DM).
     14•       Pointing to a star, the first coronagraph is inserted in the path. The bearing is rotated maximizing the contrast achieved on the SCICAM.  (use the pupil lens to see the pupils alignment maybe)?
     15•       This operation is repeated for all the coronagraphs.
    1616**Success criteria**
    17 •       Successful acquisition sequence.
     17•       All the coronograph are aligned to the true orientation of the M2 spider by maximizing the contrast at SCICAM.
     18•       Note down the contrast achieved for all the coronograph including the atmospheric conditions and the brightness of the on-axis star.
    1819**Notes**
    1920**LBTO support**
    20 •       Support from LBTI/LBTO?
    21 •       Presence of John Hill usually helps while collimating for first time.
    22 •       Steve Allenson (as the TO) will be a great asset too.
     21* SOUL-AO support
    2322**Associated SHARK-NIR personnel**
    24 •       JF, LM, MdP, MM (from AZ), DV?
