The [CII] 158$\\mu$m fine-structure line is typically one of the brightest emission lines of star-forming galaxies and thus a promising tracer of the global EoR star-formation activity. However, [CII] intensity maps at $6 \\lesssim z \\lesssim 8$ are contaminated by interloping CO rotational line emission ($3 \\leq J_{\\rm upp} \\leq 6$) from lower-redshift galaxies.
