   Created Mar 2015
   Transcription of the rezipe of Diehl et al. (2009) for consistent phase
   picking. For a given inital (the most likely) pick, the corresponding earliest
   and latest possible pick is calculated based on noise measurements in front of
   the most likely pick and signal wavelength derived from zero crossings.
