That’s interesting, it looks like we (strongly) over-subtracted the halo of this star. It looks good in DR10 :slight_smile: Halo subtraction was based on the star’s predicted brightness based on the Gaia BP,RP mags.

Huh, in Gaia-DR2 there are two stars (each with mag ~5.5) in that spot, while in Gaia-EDR3 it has merged them into a single catalog star.

Its a known binary. Not sure why the 2nd gaia source was removed for DR3.

In DR10 is a normal star.
