The current orbit of Atlas was analyzed using frequency phase space mapping. Finding that the Corotation and Lindblad resonances are separated by about 4 kilometers, the latter is related to Atlas eccentricity greater than 0.0095. Extending the Dynamic Maps concept we find, in addition to the 53:52 resonance (Cooper et al. 2015), the 55:54 resonance. Finally, we demonstrate how gravitational perturbations by Pandora contribute to additional oscillations of the critical angle for the 54:53 resonance
