P1.9 Science detector calibrations

• Phase : 1
• Status : Draft
• Category : Unpack, Assemble, Verification, and Installation (C1)
• Recurrence : once
• Duration : 1 day

Description

• Calibration and testing of the SHARK-NIR science detector

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.

SDC1	Instrumental background for science
SDC2	Instrument flat field, detector linearity and bad pixels
SDC3	Wavelength calibration
SDC4	Thermal background
SDC5	Detector gain
SDC6	Detector persistence
SDC7	Spectral resolution
SDC8	Ghost calibration
SDC9	Filter wheels reproducibility monitoring

Success criteria

• linearity as expected
• bad pixels mask created
• bias and flat took
• All individual activity (in the table) success criteria is met

Notes

• Save all the intermediate images to check the SHARK-NIR Data Reduction pipeline.
