    1  == P3.4        Pupil alignment ==
    2 •       **Phase**               :       3 
    3 •       **Status**              :       Draft   
    4 •       **Category**            :       Nighttime testing (functionality and operability) (C4)
    5 •       **Recurrence**  :       before every observing target (CI, LSS), starting from commissioning.
    6 •       **Duration**            :       30 minutes
    7 **Description**
    8 •       Alignment of the internal pupil image (PP1) with apodizer in the coronagraphic mode
    9 **Prerequisites**
    10 •       Bad pixel map, Background or Dark, Flat-field, detector RON
    11 **Procedure**
    12 •       The position of the first tip-tilt mirror (IN_TT) is optimized in order to have the first pupil image centered with the apodizer. This is obtained comparing the pupil image, formed on the SCICAM, with the image of the apodizer, obtained on the SCICAM using the calibration fiber as a source.
    13 **Success criteria**
    14 •       Expected accuracy: 0.25% of pupil image diameter ~17arcsec of the TTM ~1.5pixel SCICAM ~30μm at the level of the SCICAM.
    15 **Notes**
    16 •       Same as activity 8.2 in AD4
