In 2006, the IRIS DMC began to collect an "authoritative" set of manufacturers' recommended nominal instrument responses in SEED RESP format and publish these on the web. The goal behind the Library is to make it easier for the seismological community to both share and create metadata for common instrumentation, and to improve response accuracy for users of the data. All links to responses are queries to the NRL web service.

The High Gain Centaur models have gains 4 times that of standard Centaur models. This is not reflected in the Centaur's user interface, so the operator needs to be aware that when selecting for example 40Vpp range, the High-Gain Centaur is really operating with a 10Vpp range.

HGSProducts
Because geophones are passive sensors, nominal responses assume that the sensor is level, the coil and shunt resistances match those listed for the response, and that the preamplifier impedance of the datalogger is at least 2 orders of magnitude greater than the sensor impedance match those listed. To learn how customize these nominal responses for your specific instrumentation, here.

IESE
Because geophones are passive sensors, nominal responses assume that the sensor is level, the coil and shunt resistances match those listed for the response, and that the preamplifier impedance of the datalogger is at least 2 orders of magnitude greater than the sensor impedance match those listed. To learn how customize these nominal responses for your specific instrumentation, here. IESE does not list current damping or shunt resistor information, so responses are given with a calculated shunt resistance that assumes a total damping of 0.7071 critical. Additional parameters needed to customize these responses using the link above are as follows: | Fundamental Frequency | Mass | Open Circuit Dampiong | Intrinsic Sensitivity | | --- | --- | --- | --- | | 4.5 Hz | 0.023 Kg | 0.27 | 78.74 V/M/S | | 2.0 Hz | 0.023 Kg | 0.61 | 78.7 V/M/S |
