The Pristine survey XXIX. Data Release 2: Photometric metallicities for 15 millions stars down to G about 20.5
The Pristine survey Data Release 2 provides photometric metallicities for 15 million stars down to G~20.5, significantly expanding coverage to approximately 8,000 deg² compared to DR1. This deeper access reveals metal-poor halo stars and shows good agreement with independent DESI metallicities, offering a more complete picture of stellar populations.
