Classes

ExovistaDisk

Wavelength-interpolated 3D contrast cube loaded from ExoVista FITS.

Module Contents

class skyscapes.disk.exovista.ExovistaDisk(pixel_scale_arcsec, wavelengths_nm, contrast_cube)

Bases: skyscapes.disk.base.AbstractDisk

Wavelength-interpolated 3D contrast cube loaded from ExoVista FITS.

Attributes:

pixel_scale_arcsec: Pixel scale [arcsec/pixel]. wavelengths_nm: 1-D wavelength grid [nm], shape (n_wl,). contrast_cube: Contrast cube, shape (n_wl, ny, nx).

Parameters:

• pixel_scale_arcsec (float)

• wavelengths_nm (jaxtyping.Array)

• contrast_cube (jaxtyping.Array)

pixel_scale_arcsec: float

wavelengths_nm: jaxtyping.Array

contrast_cube: jaxtyping.Array

_contrast_interp: interpax.CubicSpline

surface_brightness(wavelength_nm, time_jd, incl_deg, pa_deg)

Contrast map at the requested wavelength, shape (ny, nx).

time_jd, incl_deg, and pa_deg are part of the AbstractDisk interface but ignored here: the cube is a single time snapshot with disk geometry already baked in by the loader.

Parameters:

• wavelength_nm (jaxtyping.Array)

• time_jd (jaxtyping.Array)

• incl_deg (jaxtyping.Array)

• pa_deg (jaxtyping.Array)

Return type:

jaxtyping.Array

spatial_extent()

Return (width_arcsec, height_arcsec).

Return type:

tuple[float, float]

__repr__()

One-line summary of cube shape, pixel scale, and wavelength grid.

Return type:

str
