4.11 Disk: Jets investigated with long-slit spectra

• Phase : 4
• Status : Draft
• Category : Science verification / Early science (C7)
• Recurrence : once after the completion of nighttime testing and performance check
• Duration : 1 night(s)

Description

Prerequisites

• Authorize SHARK-NIR on the SX side.
• Atmospheric conditions: CLEAR
• Bad pixel map, Background or Dark, Flat-field, distortion map
• Cloud Cover : no clouds
• Astronomical Seeing : 0.8" or better
• Sky Background : Any
• Water Vapor : low
• Timing Windows : no major limitation as the observation will be done in filed stabilized mode
• Observing Targets : TBD (same than in Section 4.10)
• Observing Filters : LSS observing mode, no filter
• Detector Mode, DIT: according to the target brightness
• Daytime Calibration Data required: dark/background, flat
• Nighttime Calibration Data required: none

Procedure

• We observe for more then 1 hour the star with the LSS observing mode. We alternate the position of the slits from the position of the jet to outside the companion position to be able to create a library

of images to be used to subtract the speckles. An observation of the star without coronagraphic mask is also requested to allow a proper flux calibration. Also, we need an observation of a standard star to be able to properly reduce the telluric lines. The observation is performed in field stabilized mode.
