Narrative:

Air carrier flight syr-clt shine 5 arrival, approaching hmv, assigned heading off of arrival (uncertain of heading). After 2-3 mins, assigned a new heading of 200 degrees, I think, and then told to intercept 314 degree radial from clt VOR and resume shine arrival. I mistakenly set up intercept on 156 degree radial from hmv on FMC. After a short time, ZTL noticed deviation, told me of my mistake and issued a new clearance. Flight was completed uneventfully. I don't know if there were any traffic conflicts with other aircraft. Solution: be more careful with automated flight guidance system. Company policy is for both pilots to agree before a course change is 'executed' in the FMC. Captain also failed to detect error.
