| Abstract: |
How similar are two spectra? There are many methods to define the
similarity of spectra. Usually, a value describes how two spectra are
alike. In this paper, we introduce a new criterion which will judge
whether two spectra are similar in flux. We apply this criterion on LAMOST production. Using distribution architecture, we can search one
spectrum's similar spectra in 2 seconds in a sample which contains more
than 240,000 spectra templates. Using this technology, we can use
hundreds of thousands of observed classified spectra with various quality
as templates for stellar spectra. |
