This is an erratum for the paper “The Fornax Deep Survey (FDS) with VST VI. Optical properties of the dwarf galaxies in the Fornax cluster”. We noticed two mistakes in Fig. 21 of the original paper that have a slight effect on the shown ram pressure stripping radii, but do not change conclusions of that figure. In addition, in the original paper, we had calculated cluster-centric distances of objects incorrectly in some parts of our analysis, which slightly affects the appearance of several figures in the original paper. We show here the corrected versions of all the figures that were affected by this mistake. In this Letter, we use original numbering of the figures to avoid confusion. The conclusions and findings of the original paper are not altered by these mistakes. The first mistake in Fig. 21 of the original paper is that wrong velocities were used when estimating the stripping radii of the ram pressure stripping. This error was caused due to the first author’s experiments of how the different cluster-centric velocities of the infalling galaxy affect the stripping radii. The results of these tests were mistakenly saved to the figure that appears in the published version. In the left panel of Fig. 21, we show the ram pressure stripping radii when using those velocities stated in the original text and legend. (Figure Presented).
