Implication

Randomized trial classifies astronomical objects with photometric redshifts, indicating effective categorization of stars, galaxies, and quasars.

Key Points

The aim is to provide a comprehensive object catalogue for the Chandra Deep Field South, facilitating the classification of astronomical bodies and estimating their photometric redshifts.
Generated a catalogue covering 63,501 objects with data in 17 passbands from 350 to 930 nm.
Analyzed nearly 1,000 spectroscopically identified objects to validate classification and redshift accuracy.
Characterized performance for classifications into stars, galaxies, and quasars with corresponding luminosity data.
Quasar selection is nearly complete for luminosities above MB = -21.7 with minimal contamination.
Photometric redshifts for quasars are accurate within 5000 km/s; for galaxies, 1% at brighter magnitudes and 10% at fainter magnitudes.
Star selection is complete at specific luminosities with enhanced accuracy for M stars.
