astrotools

astrotools is a personal toolbox of astronomy analysis code from my research. It’s a mix of reusable helpers, small scripts, and notes for time-series data, spectra, SED analysis, and more.

Spectral utilities

• Modules live under astrotools.spectral
• Model grids default to /data/models/ELM (override with ASTROTOOLS_MODEL_DIR)
• Atmosphere classes supported by load_atmosphere_grid: ELM/DA (H-rich) and DB (He-rich)

Migration notes (from scattered scripts)

• Legacy SPECTRAL_UTILS names are available as compatibility aliases in astrotools.spectral:
  • load_models, interpolate, interpolate_linear
  • broadening, convert_flux_density, convert_to_physical
  • shift_wavelength, clip_outliers, linear_model, line_model, extract_lines
• Binary/SED helpers extracted from Joint.py are available in astrotools.spectral:
  • roche_lobe_radius (alias: calculate_radius)
  • secondary_rv_semiamplitude (alias: calculate_rv)
  • log_surface_gravity (alias: calculate_logg)
  • gaussian_log_probability (alias: gauss_prob)
