 **Description**
 - To verify the SHARK-NIR internal fast tip-tilt loop (using CRED2 and SHARK-NIR ALPAO DM) using the ARGOS light source (only at zenith) for various seeing conditions (0.5", 0.8") simulated at the ASM. This test will verify if the correction of the fast tip-tilt loop is affected by the residual turbulence for star at different magnitudes.
+- Before or after the previous test, we will also perform a short test (about 30 mins long) to find the center of the field. 
 
 **Prerequisites**
 - Knowledge of Argos light source magnitude and the possibility of tuning its brightness.
 
-**Procedure**
+**Procedure for the Tip-Tilt internal fast loop test**
 - Use ARGOS light source (to be used only at zenith) and direct light towards SHARK-NIR.
 - Close the SOUL AO loop to have the best ASM shape. Keep the ASM static with the best shape.

+- Close the SOUL AO loop to have the best ASM shape. Keep the ASM static with the best shape.
+- Close the SHARK-NIR internal tip-tilt loop.
+- Move the derotator in step of 10 degrees (TBD) and take an image at each position. From the data taken, estimate the center of the field.

 **Success criteria**
 - SHARK-NIR fast tip-tilt loop working efficiently within the requirements in all the seeing conditions.
