SpeXtra

A python tool to manage and manipulate astronomical spectra

Description

speXtra is a python tool to download, load, display and manipulate spectra of astronomical sources. It has developed to provide spectral sources to ScopeSim but it may be helpful for other purposes too.

speXtra stands in the shoulder of giants: synphot and astropy.

To install spextra simply run:

pip install spextra

Soon a PyPi version will be available

Functionalities

speXtra is able to:

• Download spectra from a database and return it in format compatible with synphot format.

from spextra import Spextrum
sp = Spextrum("kc96/s0")

and it will load the S0 galaxy template of the Kinney-Calzetti spectral library. To quickly plot the resulting spectra, simply type

sp.plot()
