Is star/galaxy/QSO separation available in the DP1 Object table?

I’m looking at the DP1 objects catalogue table and wondering — is any star/galaxy/QSO classification already available for objects in DP1?
If not, what’s the recommended way to separate them — extendedness via PSF vs. model flux, or something else?

Hi @viveikjha – the schemas for DP1 tables, including the object table, are available at:

https://sdm-schemas.lsst.io/dp1.html

The object table has a column called refExtendedness which is recommended for star/galaxy separation. Thanks very much…

Thanks for the help.
