WEDA: A Weak Emission-Line Detection Algorithm Based on the Weighted Ranking

The Hα emission line in rest wavelength frame of optical spectra is valuable characteristics for nebulae detection. Searching and recognizing the spectra with Hα emission line from massive data are necessary for the further study, while the most of methods existed currently do...
