== P2.2 Instrument operability and functioning == • **Phase** : 2 • **Status** : Draft • **Category** : Daytime testing (functionality and operability) (C2) • **Recurrence** : after instrument installation at telescope platform • **Duration** : 1 day **Description** • The functionality and operability of individual components/subsystems are tested. This is followed by the checking of the internal alignment of the instrument using the light source within. The final step is the performance of the system. **Prerequisites** • All electronics and services up and running. **Procedure** • Initialize all the motors/sub-systems. • Check the functionality of all the motors (home position, named/nominal positions, and reaching software limits). • Check the working of all the light sources. • Using the on-axis diffraction-limited light source, check the internal alignment of the SHARK-NIR. • Finally, the performance of the system is again verified after the installation.?? * Alignment of the TECCAM (hot pixel) **Success criteria** • Motors and light sources working as they should. • The internal alignment is preserved. • Performance of the system is acceptable. **Notes** **LBTO support** **Associated SHARK-NIR personnel** **Date performed and by whom** **Comments** MB:I believe checking functionality of motor is included in previous point . However in success criteria is correct what you wrote MB: performance checks might require more time than foreseenYOU ARE RIGHT. HERE WE ARE CEHCKING ONLY FUCNTIONALITY or performance??? LM: I would see in this phase a check of the internal alignment by checking at the position of the PSF both on the SCICAM and on the TECCAM, and at the position of the pupil on the SCICAM. Finally, another check of on-axis optical quality using phase diversity and of the relative positions of the coronagraphic masks. If the internal alignment is preserved I would not expect any change in the performance of the system. Moreover, "performance" is a rather general word, a complete check of the performance of the instrument is the scope of the commissioning, so performance will be tested by completing all the activities listed in the commissioning plan. I do not understand what "Alignment of TECCAM" means..
