constant_width

pyrt.observation.constant_width(center_wavelength, width)[source]

Create an instance of Spectral assuming the wavelengths all have a constant spectral width.

Parameters

  • center_wavelength (ArrayLike) – The center wavelength [microns] of each spectral bin.

  • width (float) – The width of each spectral bin.

Raises

  • TypeError – Raised if any values in the input arrays are nonnumerical.

  • ValueError – Raised if the inputs contain values outside of 0.1 to 50 microns (I assume this is the valid range to do retrievals).

Return type

pyrt.observation.Spectral

Examples

Create an instance of Spectral for an observation taken at 1 to 3 microns in 1 micron increments, with each channel having a 50 nm spectral width.

>>> import numpy as np
>>> from pyrt.observation import constant_width
>>> center = [1, 2, 3]
>>> width = 0.05
>>> constant_width(center, width)
