The disk inclination and position angle are determined to be $i=49.5\\degr\\pm3.5\\degr$ and $\\mathrm{PA}=18.2\\degr\\pm3.5\\degr$ and the dusty and gaseous disk are detected up to $\\sim220$ au and $\\sim400$ au from the star, respectively. Most importantly, our continuum observations indicate that the cavity size in the mm-sized dust distribution must be $\\sim97$ au in radius, the largest cavity observed around a T Tauri star. Our data clearly confirms the presence of \\co(2-1) well inside the dust cavity.
