Software to compute the time-scale phase-weighted stack (ts-PWS), including the two-stage stack and the unbiased phase coherence strategies (Ventosa et al., GJI 2017). The software packages of fast phase cross-correlation and ts-PWS stacking are basic building blocks in the design of efficient signal extraction methods from interstation correlations. Main features Fast: The time-frequency expansion used in the ts-PWS is implemented using frames of wavelets (Morlet and Mexican hat wavelets are available). The most demanding operation is conventionally reading the data. Better filtering: The two-stage stacking and the unbiased phase coherence help to reduce signal attenuation and to increase noise attenation. Simple setup: All parameters are automatically set, e.g., when w0, Q or number of cycles is changed the parameters describing the frame are adapted accordingly. Resampling techniques: The bootstrap and jackknife techniques can be applied to build a pull of stacked sequences for a subsequent error analysis. The ts-PWS version 1.0 is available in Ventosa (2018), DOI:10.5281/zenodo.1154588.
