P3.16 Instrumental throughput and absolute flux calibration

• Phase : 3
• Status : Draft
• Category : Nighttime testing (functionality and operability) (C5) + Nighttime calibration (C6)
• Recurrence : once every month starting from commissioning and then on request for accurate photometry (using CI and DBI).
• Duration : 4 hours

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 required filters.

Templates

• SHARKNIR_lss_cal_AbsoluteFlux (not released)

Success criteria

• Flux measurement better than 10%

Notes

• Same as activity 7.3 in AD4

LBTO support

• AO support
