Access to Catalogues: Example #1

Archive Science Group 4 months ago updated 3 months ago 0


Several catalogues are available in the ESO Archive containing a variety of information ranging from photometry of sources extracted from imaging data products, redshifts and additional physical parameter from spectra, weak lensing shear measurements, etc.

These catalogues can be accessed via the web query interface or programmatically.

For instance, you can follow this notebook to create the image on the right, showing the distribution of point (blue) and extended (red) sources in the colour-colour plane obtained from the VISTA Kilo-degree Infrared Galaxy Survey (VIKING).

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