Parameters:

  • hf (numpy.ndarray of floats) – SAC float header array

  • hi (numpy.ndarray of ints) – SAC int header array

  • hs (numpy.ndarray of str) – SAC string header array

  • data (numpy.ndarray of float32) – SAC data array

  • tests (str) – One or more of the following validity tests: ‘delta’ : Time step “delta” is positive. ‘logicals’ : Logical values are 0, 1, or null ‘data_hdrs’ : Length, min, mean, max of data array match header values. ‘enums’ : Check validity of enumerated values. ‘reftime’ : Reference time values in header are all set. ‘reltime’ : Relative time values in header are absolutely referenced. ‘all’ : Do all tests.

Raises:

obspy.io.sac.util.SacInvalidContentError if any of the specified tests fail. ValueError if ‘data_hdrs’ is specified and data is None, empty array, or no tests specified.
