Time function

[Navids94]

Hello! I would like to know whether the Ricker, Triangle, BruneSmoothed and C6SmoothBump functions generate displacement or velocity directly. As far as I know, the Gaussian and Liu functions generate velocity and displacement respectively. I have observed that my simulation has good correlation with the recorded data in the time series, but there is a factor of 100 difference in the frequency domain(the simulation is larger). I have tried changing the corner frequency in the input file, but it hasn't made a significant difference. I am unsure of the reason behind this discrepancy in the frequency domain, but I want to change the time function to see if that helps. Thank you.
