EstimateSpectralBinning

It computes spectral binning useful to produce the radiometric tables

Module Contents#

class EstimateSpectralBinning[source]#

Bases: exosim.tasks.task.Task

It computes spectral binning useful to produce the radiometric tables

Returns:

wavelength bins table

Return type:

astropy.table.QTable

Raises:

  • TypeError: – if the output is not QTable

  • KeyError: – if a column is missing in the output QTable

Notes

This is a default class with standardised inputs and outputs. The user can load this class and overwrite the “model” method to implement a custom Task to replace this.

execute()[source]#

Class execution. It runs on call and executes all the task actions returning the outputs. It requires the input with correct keywords

model(wl_grid, parameters)[source]#

It runs a dedicated method if the channel is a spectrometer or a photometer.

Parameters:

  • wl_grid (Quantity (optional)) – focal plane wavelength grid. Useful for spectrometers. Default is None.

  • parameters (dict) – dictionary contained the channel parameters. This is usually parsed from LoadOptions

Returns:

wavelength bins table

Return type:

astropy.table.QTable

Raises:

AttributeError: – if the channel type is not spectrometer or photometer

wavelength_table_spectrometer(description, wl_grid)[source]#

It returns the wavelength table for a spectrometer. The wavelength grid can be estimated in 2 modes:

  • native mode. If targetR is set to native the wavelength grid computed is the pixel level wavelength grid, where each bin is of the size of a pixel;

  • fixed R mode. If targetR` is set to a constant value, the wavelength grid is estimated using wl_grid.

Parameters:

  • description (dict) – dictionary contained the channel parameters.

  • wl_grid (Quantity) – wavelength grid.

Returns:

wavelength bins table

Return type:

astropy.table.QTable

Raises:

KeyError – Channel targetR format unsupported

wavelength_table_photometer(description)[source]#

It returns the wavelength table for a photometer. It is estimated as the central wavelength of the photometer with a bin width equal to the wavelength band.

Parameters:

description (dict) – dictionary contained the channel parameters.

Returns:

wavelength bins table

Return type:

astropy.table.QTable
