AbstractConsensus quantification regarding experimental data often reveals valuable information for researches. For instance, solar irradiance exerts synchronization effects on Earths regional climate and the daily rhythm of cell division is controlled by the cells circadian clock. In the context of coupled oscillators, one may directly compute the norm of the differences between oscillators states over time. If after the transient these values become sufficiently small, it indicates a regime close to full synchronization, when oscillators converge to a common trajectory. On the other hand, several regimes commonly found in Nature can be characterized just via phase assignment. That is, one needs to specify coordinates along the limit cycle, with growth in the direction of the motion and 2Pi gain after each cycle. However, there seems to be no rigorous way to solve this problem for arbitrary chaotic systems. Thus, how do we compare phase assignment methods? For this purpose, we introduced in a previous work the Double Strip Test Bed (DSTB), which is a methodology to construct time series similar to the ones originated from chaotic oscillators. This approach relies on the well-known Kuramoto Model, and a transformation of its phase variables by embedding them into a three dimensional surface, in such a way to obtain curves with known phase variables a priori. We present here a numerical study regarding four methods commonly found in the literature: the classic Arctan method, the Arctan Method using the derivative of the time series, the Poincaré Surface Method and the Hilbert Transformation method. These techniques were applied to time series from two versions of the Rossler chaotic oscillator, coherent and non-coherent, and also from the DSTB. In the simplest case, the coherent one, all methods provided similar outcome. By analyzing the other scenarios, we point out advantages and limitations of each method.
