P3.18 Atmospheric calibration and absolute flux calibration

• Phase : 3
• Status : Draft
• Category : Nighttime testing (functionality and operability) (C4)
• Recurrence : once at commissioning and then for each LSS observation observations.
• Duration : 1 hour

Description

• Atmospheric calibration to remove telluric atmospheric features from the stellar spectrum and get absolute flux calibration per spectral resolution element.

Prerequisites

• Authorize SHARK-NIR on the SX side.
• Atmospheric conditions: AO working conditions.
• Bad pixel map, Background or Dark, Flat-field, wavelength calibration.

Procedure

• Observe the spectrum of a featureless (and/or standard) star at similar airmass that of the science target.

Success criteria

• Better than 10% for absolute flux calibration and for average residuals from telluric removal.

Notes

• Same as activity 7.4 in AD4

LBTO support

• SOUL-AO support
