Access to Catalogues: Example #4
Archive Science Group 2 years ago • updated 2 years ago • 0
Catalogues ingested in the ESO archive via the Phase 3 process are accessible via the ESO Archive Science Portal, or via the Catalog Facility, or programmatically via the `tap_cat` service.
Information from different catalogues can be cross-matched and compared. For instance, in the Figure on the top we plot the distribution the physical properties (effective temperature and gravity) of stars derived from with high-resolution spectroscopic observations of stars by the AMBRE and GAIAESO collections.
The walk-through to obtain this information is illustrated in this notebook (it requires the installation of the un-official ESOAsg python package).
