Caption: Figure 2.

Visual extinction ( A _V ) maps in M83. These two A _V maps are derived from the Hα/Hβ (left) and Hα/Paβ (right) line ratios. The southern and northern pointings have been mosaiced, and the colorbar shows the value of A _V in magnitudes. The margins of the FoVs are depicted by the black dash lines for both the northern and the southern pointings.
