[Instrument]

This section deals with passing the forward model through some form of noise model.

The instrument function in TauREx3 serves to generate a spectrum and noise from a forward model.

Including a noise model in the TauREx3 input makes the output file capable of being used as an observation in the retrieval. It is also capable of fitting itself (See TauREx Spectrum)

Instrument models consume the active binner. In practice this means response functions, per-channel broadening profiles, and wavelength shifts should be configured on [Binning] when they are part of the instrument transfer function rather than the atmospheric model itself.

The instrument is defined by the instrument variable:
  • snr

    • Signal-to-noise ratio instrument

    • Class: SNR

  • custom

SNR

instrument = snr A very basic instrument that generates noise based on the forward model spectrum and signal-to-noise ratio value. Uses the native spectrum as the grid, unless a Manual binning is defined in which case that is used as the grid.
