+•       **Status**              :       Draft    
+•       **Category**            :       Daytime testing (functionality and operability) (C2)
+•       **Recurrence**  :       once at commissioning
+•       **Duration**            :       3 hour(s)
+**Description**
+•       This activity corresponds to the flexure tests for the SHARK-NIR. 
+**Prerequisites**
+•       If relevant, estimate and remove the NCPA using phase-diversity method.
+•       RR mounted on SX side.
+**Procedure**
+•       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**
+•       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?
+**Associated SHARK-NIR personnel**
+•       JF, LM, MdP
+**Date performed and by whom**
