We present a new strategy for the pre-processing filteringtechniques of the LIGO strain of the GW150914\cite{Abbott:2016blz,TheLIGOScientific:2016wfe} eventthat intends to extract as much physical information as possible,minimizing the use of prior assumptions,and avoiding transformations of the astrophysical signal.We apply this to the search of similar signals in two detectors.We show the tensor polarization (spint 2 nature) of the GW150914 signal.
