ECHOMOP—Echelle Data Reduction Package
echomop provides facilities for the extraction of spectra from 2-D data frames. These data can be single-order spectra, or multi-order échelle spectra.
A substantial degree of automation is provided, particularly in the traditionally manual functions for cosmic-ray detection and wavelength calibration; manual overrides are available.
Features include; robust and flexible order tracing, optimal extraction, support for variance arrays, and 2-D distortion fitting and extraction.
