== [[span(style=color: green, **P3.9 Check the acquisition procedure** )]]== - **Phase** : 3 - **Status** : [[span(style=color: green, **COMPLETE** )]] - **Category** : Nighttime testing (functionality and operability) (C5) - **Recurrence** : once at commissioning - **Duration** : 2 hours **Description** - Verify the acquisition sequence for SHARK-NIR **Prerequisites** - Atmospheric conditions: should be able to see bright stars in the sky (preferably close to zenith?). - Authorize SHARK-NIR on the SX side. - Suitable bright enough target (including the possibility of performing AO). **Procedure** - Start the acquisition sequence: collimating the telescope to reduce the aberrations, close the loop and produce better ASM flat, NCPA estimation using phase-diversity algorithm, close SHARK-NIR tip-tilt+NCPA loop, and check the PSF quality at SCICAM. - Save telemetry (open and closed loop of the ALPAO DM). **Templates** - SHARKNIR_di_acq - direct imaging mode - SHARKNIR_di_obs - direct imaging mode - SHARKNIR_ci_acq - coronagraphic mode ? - SHARKNIR_lss_acq - long slit spectroscopy mode ? **Success criteria** - Successful acquisition sequence. **Notes** **LBTO support** - AO support **Date performed and by whom**
