    99**Description**
    10 - For the correct telescope mode for SHARK-NIR, find the offset direction & magnitude (for the field-stabilized mode), verify the proper image orientation, pixel scale, field of view, and distortion at the SCICAM. Note that this may be performed with and without AO running.
     10- Proper working and tuning of the SOUL-AO parameters are verified. If minor adjustments are required, they are either implemented immediately or marked for later daytime work. Also, the SOUL AO performance is verified for various stars of different magnitudes.

    1212**Prerequisites**
    13 - Atmospheric conditions: should be able to see bright stars in the sky (preferably close to zenith?).
    14 - Authorize SHARK-NIR on the SX side.
    15 - Suitable binary or astrometric targets.
    16 - AO is running for part of the test.

    1814**Procedure**
    19 1.      Procedure for image orientation
    20         -       Select a filter
    21         -       Place the de-rotator in the nominal "zero" position.
    22         -       Issue a preset to move to a bright star (but not too bright to saturate)
    23         -       Center the star in the science channel
    24         -       Issue a pure elevation offset to the TCS of ca. 5" and verify expected motion direction on the SCICAM
    25         -       Return to the on-axis position and repeat with a pure azimuth motion.
    26         -       Issue a preset to move to a suitable astrometric binary (typically 5-8 arcsec separation) and center one star in the science channel.
    27         -       Based on the published coordinates of the binary, issue the appropriate offset to center the other star.
    28 2.      Procedure for pixel scale/ plate scale
    29         -       Select a filter
    30         -       Issue a preset to move to a suitable astrometric binary to measure pixel scale (typically 5-8 arcsec separation)
    31         -       Center the binary in the upper half of the SCICAM and take several frames. Average these frames
    32         -       Move the binary to the lower half of the SCICAM and repeat.
    33         -       Use the difference image (optionally flat-fielded) to verify the expected pixel scale. This gives two measures.
    34         -       Repeat this for other filters.
     15- AO verification procedure TBD
     16- AO performance procedure TBD

    3820**Success criteria**
    39 - The image orientation is as expected. The pixel scale and field of view of the SCICAM are as expected.
     21- The SOUL-AO system is working in tandem with the SHARK-NIR system.
     22- Acceptable improvement of the on-axis PSF for a given seeing and brightness of the star.
