Narrative:

We were given the coney climb runway 13 (lga runway 9 SID) in the clearance. For the takeoff brief, both pilots failed to read the departure SID all the way through. Both pilots read clearance up to the speed/clear gradient chart. Clearance continues after chart, but both pilots thought procedure ended there. After takeoff, departure control questioned our heading and gave us a vector to get back on course. Suggestion: better vigilance by the pilots. But we both agreed that since we both made the same error in reading the chart, the climb data would be better at the bottom of the coney climb clearance instead of chart dividing the clearance. We both read only up to the chart and not beyond that.

Title: HDG TRACK DEV BY AN MD80 FLT CREW WHEN DEP ON THE CONEY CLB, LGA9 SID FROM LGA.

Narrative: WE WERE GIVEN THE CONEY CLB RWY 13 (LGA RWY 9 SID) IN THE CLRNC. FOR THE TKOF BRIEF, BOTH PLTS FAILED TO READ THE DEP SID ALL THE WAY THROUGH. BOTH PLTS READ CLRNC UP TO THE SPD/CLR GRADIENT CHART. CLRNC CONTINUES AFTER CHART, BUT BOTH PLTS THOUGHT PROC ENDED THERE. AFTER TKOF, DEP CTL QUESTIONED OUR HDG AND GAVE US A VECTOR TO GET BACK ON COURSE. SUGGESTION: BETTER VIGILANCE BY THE PLTS. BUT WE BOTH AGREED THAT SINCE WE BOTH MADE THE SAME ERROR IN READING THE CHART, THE CLB DATA WOULD BE BETTER AT THE BOTTOM OF THE CONEY CLB CLRNC INSTEAD OF CHART DIVIDING THE CLRNC. WE BOTH READ ONLY UP TO THE CHART AND NOT BEYOND THAT.
