The nominal poles and zeros here desribe the long-period behavior of the STS-1. There is an additional LP filter having a single pole near 77 Hz that has been omitted. If you wish to include this pole, you can either use a nominal pole value of -483.3 radians or calculate a more precise value using the RC measurements from your instrument's calibration sheet. In addition, the calibration sheet should be used to obtain a more accurate sensitivity than the 2400 V/m/s value.
The STS-1 can be operated in 360 second or 20 second modes. Both responses are included here.
