Access to Spectroscopic Data: Example #1

The ESO Archive currently contains more than 1.7 million spectra stored in an homogeneous database.

These exquisite quality spectra can be accessed via the Archive Science Portal V2 or programmatically.

For instance, you can follow this notebook to create the image on the right. This shows the Hα line profile as observed with MUSE (red, with a resolution R~3000), XSHOOTER (blue, R~10000), and UVES (green, R~100000) how the star HD 172230. This star is part of the MUSE library of stellar spectra project (Ivanov et al. 2019).

More notebooks showing the power of the programmatic access are here.
