Description

This image had the problem arc showing in the L, R, G, and B subs. I was able to remove the arc in the Lum subs using Adam Block's Selective Rejection method as some of the L subs did not have the arc. All of the R, G, and B subs contained the arc so I removed it using the LinearStarNet script and the clone tool.
