Potential dangers of interpreting kinematic data with poor sampling. Left: source plane Hα intensity map and velocity field in this study for CSWA19 (top row) and CSWA31 (bottom row). Right: respective simulated Hα intensity map and velocity field indicating the deterioration in resolution equivalent to that for non-lensed sources studied with KMOS. In both cases, the complex morphology and velocity structure is lost in the poorer sampled data leading to the erroneous conclusion of kinematically well-ordered systems.
