skyscapes.disk.composite

CompositeDisk: sum of multiple AbstractDisk components.

Mirrors how skyscapes.scene.System composes multiple Planet objects via a tuple: a CompositeDisk holds a tuple of disk components and renders their summed surface_brightness on a shared grid.

All components must share the same spatial_extent() so the per-component rendered arrays can be added directly without resampling. Mismatched geometries are rejected at construction.

Classes

CompositeDisk

Sum of multiple disk components rendered on a shared grid.

Module Contents

class skyscapes.disk.composite.CompositeDisk

Bases: skyscapes.disk.base.AbstractDisk

Sum of multiple disk components rendered on a shared grid.

Attributes:

components: Tuple of AbstractDisk instances. At least one

component is required. All components must report the same spatial_extent() so their rendered (ny, nx) arrays sum elementwise.

components: tuple[skyscapes.disk.base.AbstractDisk, Ellipsis]

__check_init__()

Reject empty composites and mismatched component extents.

surface_brightness(wavelength_nm, time_jd, incl_deg, pa_deg)

Return the per-pixel sum of all component contrast maps.

Parameters:

• wavelength_nm (jaxtyping.Array)

• time_jd (jaxtyping.Array)

• incl_deg (jaxtyping.Array)

• pa_deg (jaxtyping.Array)

Return type:

jaxtyping.Array

spatial_extent()

Return the shared (width_arcsec, height_arcsec).

Return type:

tuple[float, float]

__repr__()

Nested summary listing each component disk.

Return type:

str
