Module Contents

class InstrumentUnknowns(sub_configdic: dict = None)

Bases: isofit.configs.base_config.BaseConfigSection

Instrument Unknowns configuration.

_channelized_radiometric_uncertainty_file_type

channelized_radiometric_uncertainty_file = None

_uncorrelated_radiometric_uncertainty_type

uncorrelated_radiometric_uncertainty = None

_wavelength_calibration_uncertainty_type

wavelength_calibration_uncertainty = None

_stray_srf_uncertainty_type

stray_srf_uncertainty = None

_dn_uncertainty_file_type

dn_uncertainty_file = None

_check_config_validity() → List[str]

class InstrumentConfig(sub_configdic: dict = None)

Bases: isofit.configs.base_config.BaseConfigSection

Instrument configuration.

_wavelength_file_type

wavelength_file = None

_integrations_type

integrations = None

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

_unknowns_type

unknowns: InstrumentUnknowns = None

_fast_resample_type

fast_resample = True

Approximates a complete resampling by a convolution with a uniform FWHM.

Type:

bool

_statevector_type

statevector: isofit.configs.sections.statevector_config.StateVectorConfig

_SNR_type

SNR = None

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

Type:

float

_parametric_noise_file_type

parametric_noise_file = None

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.

Type:

str

_pushbroom_noise_file_type

pushbroom_noise_file = None

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.

Type:

str

_nedt_noise_file_type

nedt_noise_file = None

We have several ways to define the instrument noise. The last is NEDT noise

Type:

str

_check_config_validity() → List[str]
