+•       **Duration**            :       3 days
 **Description**
-•       A bright enough on-axis star is acquired with SHARK-NIR, to define the offset to issue to the telescope for a successful pointing. Telescope collimation model is optimized for the night, if necessary.
+•       This activity corresponds to the flexure tests for the SHARK-NIR. 
 **Prerequisites**
-•       Atmospheric conditions: should be able to see bight stars on the sky (preferably close to zenith?)
+•       If relevant, estimate and remove the NCPA using phase-diversity method.
+•       RR mounted on SX side.
 **Procedure**
-•       Authorize SHARK-NIR on the SX side.
-•       Point to bright star on the sky and acquire. Once the star is at the reference pixel of the SCICAM, record the nighttime telescope collimation model for SHARK NIR.
-•       Close the loop at least with low order to save the flat for the ASM.
-•       If needed, run again the NCPA estimation and record the flat again.
-•       Go to another bright star in the field to see if the star appears immediately in the FoV of SHARK-NIR. If needed, correct the offset and record new collimation. Iterate this with another star to cross-check again.
-•       If time allows, perform NCPA within SHARK (using the phase-diversity method) and check the working the residual tip-tilt loop+NCPA at the ALPAO DM.
-•       Save telemetry (open and closed loop of the ALPAO DM).
+•       Test the positions of the various opto-mechanical components within the instrument using optical feedback while moving the telescope in elevation. 
+•       Change the velocity and acceleration of the movement of the telescope in elevation if required.
+•       Remember to perform the tests for all the observing modes (whatever possible with RR or internal light sources)
+•       You may want to disentangle the flexure of the RR while moving the telescope in elevation by comparing the optical feedback for the same movement with the internal light source.
+•       This test will also test the working of the LBTO AO system while the telescope is moving in elevation.
+•       Compare the results with that of Padova flexure tests.
 **Success criteria**
-•       First-ever ‘technical photons’ at the SHARK-NIR WFS and SCICAM.
-•       Nighttime collimation model of the SHARK-NIR is recorded.
-•       Satisfactory PSF quality with closed loop.
-•       Telemetry saved (open and closed loop of ALPAO DM) for **Phase** diversity NCPA estimation.
+•       All the images and data are saved for analysis or to create the lookup table.
 **Notes**
+•       If the test results are not satisfactory, this activity may be repeated again after making proper countermeasures to reduce the flexure.
 **LBTO support**
-•       Support from LBTI/LBTO?
-•       Presence of John Hill usually helps while collimating for the first time. 
-•       Steve Allenson (as the TO) will be a great asset too.
+* Authorize SHARK-NIR on SX side.
+* RR will be required on the SX side.
+* Support from LBT SW Team, LBTI/Arcetri team to run SOUL AO
+
 **Associated SHARK-NIR personnel**
-•       JF, LM, MdP, MM (from AZ), DV?
