Bases: obspy.core.inventory.response.ResponseStage

From the StationXML Definition:
Response: expressed as a polynomial (allows non-linear sensors to be described). Corresponds to SEED blockette 62. Can be used to describe a stage of acquisition or a complete system.

Has all the arguments of the parent class ResponseStage and the following:

  • approximation_type (str) Approximation type. Currently restricted to ‘MACLAURIN’ by StationXML definition.
  • frequency_lower_bound (float) Lower frequency bound.
  • frequency_upper_bound (float) Upper frequency bound.
  • approximation_lower_bound (float) Lower bound of approximation.
  • approximation_upper_bound (float) Upper bound of approximation.
  • maximum_error (float) Maximum error.
  • coefficients (list of floats) List of polynomial coefficients.
