    22•       **Phase**               :       3 
    33•       **Status**              :       Draft   
    4 •       **Category**            :       Nighttime testing (functionality and operability) (C4)
    5 •       **Recurrence**  :       once at commissioning
    6 •       **Duration**            :       1.5 hour
     4•       **Category**            :       Nighttime testing (functionality and operability) (C5) + Nighttime calibration (C6)
     5•       **Recurrence**  :       once at commissioning???
     6•       **Duration**            :       1 night
    77**Description**
    88•       Adjust the orientation of the coronagraphic masks with respect to the true orientation of the M2 spider by rotating the SHARK-NIR derotator.
    … …  
    1212•       Suitable bright enough star close to zenith to have negligible effects from flexures (including the possibility of performing AO).
    1313**Procedure**
    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)?
     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 pupil's alignment maybe)?
    1515•       This operation is repeated for all the coronagraphs.
    1616**Success criteria**
    17 •       All the coronagraph are aligned to the true orientation of the M2 spider by maximizing the contrast at SCICAM.
     17•       All the coronagraphs are aligned to the true orientation of the M2 spider by maximizing the contrast at SCICAM.
    1818•       Note down the contrast achieved for all the coronagraphs including the atmospheric conditions and the brightness of the on-axis star.
