redmonster performs automated redshift measurement, physical‑parameter estimation, and spectral classification of 1D astronomical spectra. This set of Python utilities outputs the best‑fit model, redshift, classification, and derived parameters in standard formats for downstream analysis. The repository includes templates, configuration files, and documentation to enable flexible redshift and parameter estimation workflows.
