    79**Description**
    8 •       The field stabilized mode or in other words, the working of the bearing tracking service will be tested.
     10- Evaluate the performance of the internal tip-tilt (TT) loop of SHARK-NIR for stars of varying brightness.
     11
    912**Prerequisites**
    10 •       Atmospheric conditions: AO working conditions.
    11 •       Authorize SHARK-NIR on the SX side.
    12 •       Targets (star cluster) near zenith and horizon (say airmass of 2).
     13- Atmospheric conditions: TBD
     14- Authorize SHARK-NIR on the SX side.
     15- Stars (of known brightness from 8mag-13mag in R band) as targets.
     16- AO is working.
     17
    1318**Procedure**
    14 •       Select the target near airmass 2. There should be stars spread across the entire SCICAM, preferably close to the edges as well.
    15 •       Start the bearing tracking services (field-stabilized mode).
    16 •       Take short-exposure images for a duration of ##minutes.
    17 •       Check if the positions of these stars.
    18 •       Repeat the same for the target close to the zenith.
    19 •       The above may be repeated for a target where the rotation of the bearing is in the opposite direction as of the above tested one.
     19- Run the internal TT loop after the star is acquired and the AO loop is closed.
     20- Take unsaturated images of the star for a given (?) science filter before and after the internal TT loop closure in the SCICAM.
     21- Take data in TECCAM simultaneously.
     22- Use data to estimate the improvement of the residual jitter after the TT loop is closed.
     23- Repeat for different star magnitudes.
     24- should we perform as a function of elevation as well? We can choose stars accordingly, then?

    2028**Success criteria**
    21 •       The bearing tracking service works well and the field is stabilized within the precision needed.
     29- Estimate the residual jitter after SOUL-AO is closed for a given seeing and star brightness.
     30- Checking the working and performance of the internal TT loop.
     31- Quantify and numbers to add?
