Complete reference for all 183 spectroscopic features extracted by AstroSpectro in spectro_only=True mode.

How AstroSpectro's FeatureEngineer module extracts 183 physics-based spectroscopic features from LAMOST spectra.

Theoretical foundations of spectroscopic feature extraction in AstroSpectro: the Physics-Informed approach, the 6 descriptor families, spectro_only mode, and a SHAP check of how much of the model's attribution comes from physical features.
