P3.17 Instrumental throughput and absolute flux calibration

• Phase : 3
• Status : Draft
• Category : Nighttime testing (functionality and operability) (C4)
• Recurrence : once every month starting from commissioning and then on request for accurate photometry (using CI and DBI).
• Duration : 1 hour (per configuration, also depends on mag of star)

Description

• Throughput calibration to obtain absolute flux calibration of science targets.

Prerequisites

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

Procedure

• Observe a spectro-photometric standard star of known magnitude with no coronagraph and for required filters.

Success criteria

• Flux measurement better than 10%

Notes

• Same as activity 7.3 in AD4

LBTO support

• SOUL-AO support
