We present 80 stellar and ionised gas velocity maps from the Calar AltoLegacy Integral Field Area (CALIFA) survey in order to characterize thekinematic orientation of non-interacting galaxies. The study of galaxies inisolation is a key step towards understanding how fast-external processes, suchas major mergers, affect kinematic properties in galaxies. We derived theglobal and individual (projected approaching and receding sides) kinematicposition angles (PAs) for both the stellar and ionised gas line-of-sightvelocity distributions. When compared to the photometric PA, we find thatmorpho-kinematic differences are smaller than 22 degrees in 90% of the samplefor both components; internal kinematic misalignments are generally smallerthan 16 degrees. We find a tight relation between the global stellar andionised gas kinematic PA consistent with circular-flow pattern motions in bothcomponents. This relation also holds generally in barred galaxies across thebar and galaxy disk scales. Our findings suggest that even in the presence ofstrong bars, both the stellar and the gaseous components tend to follow thegravitational potential of the disk. As a result, kinematic orientation can beused to assess the degree of external distortions in interacting galaxies.
