Equivalent width of the Hβ emission line and its underlying continuum are shown along the P.A. values 60°, 150°, 240°, and 330° as determined from the WFC3 F547M and F487N images. Decreasing equivalent width values indicate relatively stronger continuum values. Most of the regions contaminated by starlight have been edited out.
