Narrative:

While working departure control, the tower coordinated a turboprop on runway heading 180 degrees and a jet inside of him on a 200 degree heading. I approved it. A few mins passed and the turboprop checked in. Out of habit I turned the turboprop wbound on course. As soon as he got in the turn the jet came off on the 200 degree heading. As soon as he checked in I remembered the coordination, stopped the jet at 4000 ft and turned him sbound. Separation was 800 ft, traffic issued, and conflict resolved.

Narrative: WHILE WORKING DEP CTL, THE TWR COORDINATED A TURBOPROP ON RWY HDG 180 DEGS AND A JET INSIDE OF HIM ON A 200 DEG HDG. I APPROVED IT. A FEW MINS PASSED AND THE TURBOPROP CHKED IN. OUT OF HABIT I TURNED THE TURBOPROP WBOUND ON COURSE. AS SOON AS HE GOT IN THE TURN THE JET CAME OFF ON THE 200 DEG HDG.
