noobase (Rust core)

Foundational pure-function utilities for astronomy analysis.

This is the Rust core of the noobase project. See the project README for overview, quick start, and Python bindings.

Public surface

  • axis::Grid — 1-D monotonic axis
  • axis::overlap — overlap-weighted rebin primitives
  • convolve — pure 1-D / axis / 2-D correlation kernels, gaussian1d, and NaN-as-missing renormalized variants (shared by image and spectroscopy::lsf)
  • spectroscopy::Spectrum — spectrum container with optional error / mask
  • spectroscopy::LsfSpec + Spectrum::convolve_lsf — Gaussian LSF broadening for noise-free spectral templates
  • spectroscopy::synthetic_photometry::{synthetic, SyntheticOperator} — synthetic photometry through transmission curves
  • image::reproject_exact — surface-brightness-conserving image reprojection via planar polygon clipping (rayon-parallel)
  • image::{convolve_psf, convolve_gaussian_axis} — true 2-D PSF convolution and 1-D Gaussian axis correlation / matched filtering
  • image::stamp::build_stamp — point-source recenter + fixed-window stamp extraction (sub-pixel centroid recorded, not applied)
  • image::psf — oversampled-ePSF / extended-PSF construction stack: build_epsf, build_extended_psf, plus the robust_combine / solve_flux_background / stitch_psf leaves and the render / accumulate adjoint pair
  • aperture::region_growing::grow_mask — adaptive aperture mask via heap-driven greedy growth from one or more seed pixels, terminated by an inner-annulus SNR stop and a radial-gradient stop (each with independent hysteresis); optional LabelInput whitelist gates which segmentation labels the mask may enter
  • Float — single trait re-export at the crate root for downstream generics; every other public name is reached through its submodule (e.g. noobase::axis::Grid, not noobase::Grid)

Examples

use ndarray::{Array1, Array2};
use noobase::axis::{Grid, GridKind};
use noobase::image;
use noobase::spectroscopy::{LsfSpec, Spectrum};

let wavelength = Grid::<f64>::linspace(1.0, 5.0, 200, GridKind::Centers);
let flux = Array1::from_elem(200, 1.0);
let template = Spectrum::new(wavelength, flux, None, None).unwrap();
let broadened = template.convolve_lsf(LsfSpec::ConstantR(3000.0)).unwrap();

let image_in = Array2::<f64>::ones((32, 32));
let psf = Array2::<f64>::from_elem((3, 3), 1.0 / 9.0);
let convolved = image::convolve_psf(image_in.view(), psf.view());
assert_eq!(broadened.n_bins(), 200);
assert_eq!(convolved.dim(), (32, 32));

Status

Pre-1.0, API unstable. Breaking changes expected between minor versions.
