AtmosphereResult¶

class nyx.core.records.AtmosphereResult[source]¶

Bases: Module

Output of atmosphere evaluation, consumed by the render loop.

extinction_hp and scattering_map cover the upper hemisphere only (nsky pixels, HEALPix RING ordering); npix is the full-sphere count, so that apply_extinction() can return a full map.

Attributes Summary

`extinction_hp`
`n_wvl`	Number of wavelength bins.
`npix`
`nsky`	Number of hemisphere sky pixels.
`scattering_map`

Methods Summary

`apply_extinction`(sky_radiance, bandpass)	Band-integrate radiance through line-of-sight extinction.
`apply_scattering`(sky_radiance_obs, bandpass)	Scatter radiance into the FOV grid, one observation at a time.

extinction_hp = <dataclasses._MISSING_TYPE object>¶

n_wvl¶: Number of wavelength bins.

nsky¶: Number of hemisphere sky pixels.

scattering_map = <dataclasses._MISSING_TYPE object>¶

Methods Documentation

apply_extinction(sky_radiance, bandpass)[source]¶

Band-integrate radiance through line-of-sight extinction.

Parameters:

sky_radiance (jax.Array, shape (nsky, n_wvl))
bandpass (jax.Array, shape (n_wvl,))

Returns:

Full-sphere HEALPix array, zero below the horizon; hemisphere pixels lead it in RING ordering.

Return type:

jax.Array, shape (npix,)

apply_scattering(sky_radiance_obs, bandpass)[source]¶

Scatter radiance into the FOV grid, one observation at a time.

Parameters:

sky_radiance_obs (jax.Array, shape (nsky, n_wvl))
bandpass (jax.Array, shape (n_wvl,))

Return type:

jax.Array, shape (n_lon, n_lat)
