speXtra#
speXtra
is a python
library for managing and manipulating astronomical spectra.
Under the hood it packages many synphot
workflows to perform typical
treatment of astronomical spectra, including scaling, binning, smoothing, redshifting, etc.
speXtra
does not make measurement on the spectra, except obtaining magnitudes.
speXtra
comes with a built-in database
to facilitate the access
to commonly used spectral templates, extinction curves and filters.
