Caption: Figure 2.

Top left: a 500 × 400 pixel cutout of the RX Cam reference frame. Top right: a 3D visualization of the 5 × 5 δ-function kernel used to convolve the reference frame (top left) to match a typical science frame (bottom left). Bottom left: a cutout of the same area for a typical science frame in the RX Cam image sequence. Bottom right: residuals after subtraction. All images are displayed using the same logarithmic stretch; colors have been inverted for clarity.
