SDC3 Wavelength calibration

  • Phase : 1
  • Status : COMPLETE
  • Category : Daytime calibration (C3)
  • Recurrence : every night when LSS observing mode is used.
  • Duration : 10 minutes (this duration is valid only during regular operations, i.e., after commissioning)

Description

  • Determine the central wavelength of each pixel for the long split spectroscopy observing mode.

Prerequisites

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

Procedure

  • This calibration is performed illuminating the slit with the spectral calibration lamps with at least 5 known emission lines; background exposures with lamps switched off are required.

Templates

  • SHARKNIR_lss_cal_Wavelength

Success criteria

  • LRS: 10 nm (goal 5 nm), MRS: 1 nm.

Notes

  • Same as activity 7.10 in AD4
