4.4 Disk: Coronagraphic imaging of stellar jets

• Phase : 4
• Status : Draft
• Category : Science verification / Early science (C8)
• Recurrence : once after the completion of nighttime testing and performance check
• Duration : 1 night(s)

Description

• Disk: Coronagraphic imaging of stellar jets

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. We will consider stars with H mag in the range 4-12 (typical 7-9), R will have a similar distribution. Stars with known jets?
• Observing Filters : NB_FeII, NB_HeI and NB_PaB both using single and dual band imaging
• Detector Mode, DIT: according to the target brightness
• Daytime Calibration Data required: dark/background, flat
• Nighttime Calibration Data required: no night calibration needed

Procedure

• Observing of the target in field stabilized mode. No coronagraph used in this case to image the inner part of the system.
