Smoothed (Gaussian with r = 1.5 pix) HST negative images of the 3C 220.3 system. Images (left to right) have effective wavelengths of 606 nm, 814 nm, and 1.60 μm. Images are 9″ on a side, with north up and east to the left. System components are labeled in the center panel. The bright spot to the left of the galaxy A core in F814W is a cosmic ray which could not be removed during image drizzling (C. Leipski 2014, private communication). The 2021 Binospec slit (20″ × 1″) placement is shown in blue in panel (a) with the red box (1″ × 1″) marking the center of the slit.
