Make sure to choose the  Oct 18, 2017 [obspy-users] anomalously expensive to resample 300s 500Hz trace. First, the hilbert transform is taken to obtain the analytic signal and hence the instantaneous phase. Once a good quality image of the section is obtained, it might be necessary to resample it to match the typical dimensions of a seismic line in the project you are working on. This is then passed to a fortran script where phase correlation is performed after Schimmel et al. We want to resample but we also want # to make sure that that the peak of the source time # function is exactly hit by a sample point. obspy.

If x is a multidimensional array, then xcorr operates column-wise across all dimensions and returns each autocorrelation and cross-correlation as the columns of a matrix. pre_processing routines to resample and filter the continuous data. To show you the power of pandas, just take a look at this old tutorial, where I exploited the power of itertools to group sparse data into 5 seconds bins. These data represent predicted current distributions of all introduced mammals, birds, reptiles, amphibians and butterflies in the Middle-Atlantic region. 3. ims) Package ScottKnottESD updated to version 2. xhtmlgenindex def crosscorr (tr1, tr2): """This function takes 2 obspy traces and performs a phase crosscorrelation of the traces.
