Attributes

  • integrations Number of integrations comprising the measurement.
    Noise diminishes with the square root of this number. Applicable in concert with parametric_noise_file or pushbroom_noise_file

  • fast_resample : bool Approximates a complete resampling by a convolution with a uniform FWHM.

  • SNR : float We have several ways to define the instrument noise. The simplest model is based on a single uniform SNR number that is signal-independnet and applied uniformly to all wavelengths

  • parametric_noise_file : str We have several ways to define the instrument noise. The second option is a parametric, signal- and wavelength- dependent noise function. This is given by a four-column ASCII Text file. Rows represent, respectively, the reference wavelength, and coefficients A, B, and C that define the noise-equivalent radiance via NeDL = A * sqrt(B+L) + C For the actual radiance L.

  • pushbroom_noise_file : str We have several ways to define the instrument noise. The third option is a full pushbroom noise model that specifies noise columns and covariances independently for each cross-track location via an ENVI-format binary data file.

  • nedt_noise_file : str We have several ways to define the instrument noise. The last is NEDT noise

  • eof_path : str Path to an Empirial Orthogonal Function (EOF) file with one row per instrument channel.
