It is a space shuttle marotta valve series, which contains two outliers:

1. 600-900: Poppet pulled significantly out of the solenoid before energizing

2. 5600-5900: Poppet pulled significantly out of the solenoid before energizing

Note: This dataset slightly different from the original dataset in UCR Time Series Archive, we manually duplicate an anomaly on the date series. in order to show our definition is robust for multiple similar anomaly cases. The anomaly definition also can find the same anomaly on the original real dataset as discord definition.
