Finding chart for the confirmed variable objects in NGC 1904, using our V reference image. North is up and East is to the right. The image size is 4.44  ×  5.18 arcmin², while each stamp size is 23.7  ×  23.7 arcsec². White circles and labels indicate the locations of the variables, and each of the variables we detect in our data is shown in an individual stamp, its location marked by a cross-hair. V2 and V8 are saturated in our reference image and therefore we do not present light curves for them, but their locations are shown on this finding chart using the coordinates of Samus et al. (2009). The tidal radius r_t ~ 500′′ (Lanzoni et al. 2007) lies outside of this plot.
