hwoutils
hwoutils is the shared utility foundation for the HWO direct imaging simulation suite. It provides JAX-native physical constants, unit conversions, and flux-conserving image transforms used across:
- yippy — Coronagraph performance modeling
- orbix — Orbital dynamics and target scheduling
- coronagraphoto — Image simulation for coronagraphic observations
- coronalyze — Post-processing and SNR analysis
- hwosim — End-to-end mission simulations
Key Features
- Physical Constants — Single source of truth for SI constants, conversion factors, and astronomical quantities
- Unit Conversions — Pure JAX conversion functions (angular, flux, distance, time) with zero astropy overhead
- Image Transforms — Flux-conserving resampling, sub-pixel shifts, and cubic spline interpolation
- JAX-Native — All operations are JIT-compilable, differentiable, and GPU-accelerated
Installation
With uv (recommended):
uv pip install hwoutils
Or with pip:
pip install hwoutils
Quick Start
from hwoutils import constants as const
from hwoutils import conversions as conv
from hwoutils.transforms import resample_flux
# Convert 5 arcsec to lambda/D for a 6m telescope at 550nm
sep_lod = conv.arcsec_to_lambda_d(5.0, 550.0, 6.0)
# Flux-conserving PSF resampling
resampled = resample_flux(psf, pixscale_src=0.01, pixscale_tgt=0.1, shape_tgt=(64, 64))
