SDC7 Spectral resolution

• Phase : Any
• Status : Draft
• Category : Daytime calibration (C3)
• Recurrence : once every month starting from commissioning.
• Duration : 20 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.
