Finding chart for the confirmed variable objects in M 30, using our V reference image. North is up and east is to the right. The image size is 11.57 × 4.55 arcmin², while each stamp size is 23.4 × 23.4 arcsec². White circles and labels indicate the locations of the variables, and each of the variables we detect in our data is shown with a crosshair at the centre of an individual stamp. Note that the display scale of each stamp is different in order to make the source visible.
