This page shows the calibration history for the SLU station FVM. For each date and component, the amplitude and phase spectrum of the velocity sensitivity are presented as well as a simulated system response to a step force calibration using the response obstined from the RESP file (obtained using the command rdseed -f dataless -R) with evalresp are given in the first three figures in a row. The last two figures provide a plot of the velocity sensitivity in meters/sec and simulated step acceleration response using the polezero file obtained using the command rdseed -f dataless -p. The purpose of the step response is to verify the polarity of the system. In the same row, the responses of the different sample rates are compared if they exist.

As distributed in the SEED response files available by ftp, ground motion up, to the north and to the east corresponds to positive numbers.
