Top panel: low-resolution Gaia XP spectrum of Gaia DR3 3547632785950758272. Middle panel: LAMOST spectrum of Gaia source id 3992861740235753216. This source is defined as DAZ+M WDMS binary in the LAMOST catalog. Lower panel: SDSS spectrum of Gaia DR3 947545965334561280. In all the panels, error in flux are represented as gray shaded region and H-Balmer lines are marked in blue. All the three spectra show the presence of strong H-Balmer emission lines and excess emission toward the bluer part of the spectrum, representing the signatures of a WD in binary with a MS star.
