Upper panel: distribution of apparent B magnitudes of the Virgo Sm, Im, and BCD galaxies in the four HeViCS fields. The red filled histogram shows the galaxies detected by Herschel. The dotted line corresponds to the completeness limit of the VCC catalogue. Lower panel: spatial distribution of the Sm, Im, and BCD galaxies in the four HeViCS fields. Grey circles show the main substructures within the cluster. Filled red, pink, and purple dots indicate FIR detections in at least two Herschel bands at distances of 17, 23, and 32 Mpc, respectively, that will be analysed in this work. Triangles with the same colour codes correspond to FIR non-detections at the three distance ranges.
