Average Lyα, Si IV, C IV, C III], and Mg II emission line profiles (from left to right) of the images A (black), B (blue), C (red), and D (green). Observations reveal significant deformations and differences between the images in the blue wings of all emission lines, with image A showing the most pronounced enhancements. In addition, image A appears to be de-magnified in the red wings. The x-axis is represented on a velocity scale, and the y-axis is in arbitrary units of flux. We note that only one epoch of observation (epoch 2) is available for the Mg II line.
