HI mass as a function of galactocentric distances for the brightest LG dwarfs, shown with black dots and adopted from Grcevich & Putman (2009), and Sculptor group dwarfs of our sample shown in red crosses. The HI masses for the Sculptor group dwarfs are adopted from Bouchard et al. (2005). The Tucana and Cetus dSphs are indicated with the black circled dots, while Scl-dE1 is marked with the red circled-cross. The Sculptor and Fornax dSphs of the LG are shown with the black plus signs. The LG transition-type dwarfs, LGS3, Phoenix, Leo T, PegDIG, are shown with the squared-dots. Arrows indicate HI upper limits. The vertical dashed line indicates the distance of 270 kpc, while the two vertical dashed-dotted inner lines indicate the 60 kpc and 90 kpc distances.
