== P1.9 Science detector calibrations == • **Phase** : 1 • **Status** : Draft • **Category** : Installation, integration, verification (C1) • **Recurrence** : once • **Duration** : 6 hour(s) **Description** • Calibration of the SHARK-NIR science detector: Gain, bad pixels, read noise, linearity, dark current, flat field, cross-talk, persistence, pattern noise. **Prerequisites** • SHARK-NIR connected to LBT network. • Electronics cabinets on. • The cryostat should be running and cooled down. • Internal alignment of the SHARK-NIR is verified. **Procedure** • check linearity, create bad pixel mask, bias calibration, master dark, and then perform the following daytime calibration procedures below. • Instrumental background for science • Instrument flat field, detector linearity and bad pixels • Wavelength calibration • Thermal background • Detector gain • Detector persistence • Spectral resolution • Ghost calibration **Success criteria** • linearity as expected • bad pixels mask created • bias and flat took **Notes** • Save all the intermediate images for Dino to check the SHARK-NIR Data Reduction pipeline. **LBTO support** **Associated SHARK-NIR personnel** • JF, LM, MdP, MM (from AZ), Dino? **Date performed and by whom**
