P3.27 Spectral resolution

• Phase : 3
• Status : Draft
• Category : Daytime calibration (C3)
• Recurrence : once every month starting from commissioning.
• Duration : 10 minutes

Description

• Measure the spectral resolution for the LSS observing mode.

Prerequisites

• Bad pixel map, Background frames

Procedure

• This calibration is performed illuminating the slit with the instrument spectral calibration lamps with known characteristics (5 emission lines). A background with lamps switched off is required.

Success criteria

• Accuracy of MRS: 0.5nm at 1.2 micron, LRS: 2 nm at 1.2 micron.

Notes

• Same as activity 9.4 in AD4

LBTO support

• Support from LBTI/LBTO?

Associated SHARK-NIR personnel

• JF, LM, MdP
