Narrative:
A navigation error occurred on the mizer 2 STAR into detroit. We were flying to the day VOR on the 206 degree radial (cleared direct) en route from nasvhille. At the VOR, the STAR called for an outbound track on the 360 degree radial. I misread the arrival as 036 degrees and tracked that radial until asked to correct back on course by ATC approximately 18 NM northeast of dayton. Supplemental information from acn 384721: normally the PNF would catch the error but I missed it. The controller seemed to help us out in good time. Also the controller indicated that our error hadn't caused a 'problem.'
