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.
