Both the CII and continuum are detected and spatially resolved. The CII line is ~1.5 times more extended than the continuum emission, showing an elongated and complex structure of approximately 3.2kpc x 6.4kpc. Two separate peaks are clearly seen (>6sigma each) in three 100 km/s width CII channel maps. The velocity field of the CII gas does not show evidence of a coherent rotation field but rather chaotic motion, reminiscent of an on-going merger.
