get_airglow

skysim.airglow.get_airglow(lam, z, p=744.0, H=2.64, Rayleigh=True, Mie=True, absorption=True)

Calculate airglow flux.

Automatically broadcasts over input arrays, but the wavelength input lam must be 1D and appear in the last axis.

The CPU time scales with the number of unique values in z so calculating on a grid with many duplicates of the same value is relatively efficient (e.g., skysim.utils.AltAzGrid).

Parameters

lamfloat or 1D array

Wavelength in nanometers.

zfloat or array

Zenith angle(s) in degrees.

pfloat or array

Pressure at the observation elevation in hPa, used for Rayleigh scattering.

Hfloat or array

Elevation of the observation in km, used for Rayleigh scattering.

Rayleighbool

Apply Rayleigh scattering effects.

Miebool

Apply aerosol Mie scattering effects.

absorptionbool

Apply molecular (but not ozone) absorption effects.

Returns

tuple

Tuple (cont, line) of arrays of airglow continuum and line fluxes in ph / (s cm2 nm).
