    99**Description**
    10 - Check the working of the internal NCPA routine (phase diversity + ALPAO-DM)
     10- Check the internal alignment of the SHARK-NIR using the light sources within.
    1111
    1212**Prerequisites**
    13 - SCICAM cooled down.
     13- SHARK-NIR is connected to the LBT network.
     14- Electronics cabinets on.
     15- The cryostat should be running and cooled down.
    1416
    1517**Procedure**
    16 - Run the Phase-diversity routine using the images taken with the SHARK-NIR internal calibration sources to measure the NCPA within (excluding the deployable arm).
     18- Use the on-axis calibration fiber, and check if the PSF position on the scientific detector is consistent with the one recorded before shipping for multiple bearing angles. Perform Phase Diversity measurement to compare the retrieved aberrations on the on-axis PSF with the ones measured before shipping.
     19- Check the pupil position at the detector and verify the consistency with the one before shipping.
     20- Check the relative alignment of the coronographic masks.

    2024
    2125**Success criteria**
    22 - Internal NCPA routine works fine and the PSF shows improvement in its quality.
     26- The on-axis spot at the SCICAM is where it should be across the bearing rotation.
     27- Use pupil images and compare.
     28- PSF quality across (using in-focus and out-of-focus fibers).
     29- Coronographic masks are co-aligned.

    2633**LBTO support**
    2734- Liquid Nitrogen refill is required in the cleanroom.
     35- We will need lights ON and OFF during the re-alignment of the instrument inside the cleanroom.
     36- 4D interferometer (TBC).
