EA/DM GX Lac has unusually broad scatter in maximum. TESS shows irregular variations well as periodic pulsations with amplitude about 0.005 mag. Does the star belong to DSCT or it has another type?
With a period of 0.77 d it can’t be a DSCT.
It is a late B-type star and the light curve shows a bump.
It is likely an ACV.
