VELOCITY.SEISN {RSEIS} | R Documentation |
Velocity Seismogram
Description
Removes seismic instrument response and corrects for sensitivity of seismoc instrument, returning units of m/s rather than volts.
Usage
VELOCITY.SEISN(TH, sel = 1:length(TH$JSTR), inst = 1,
Kal = Kal,waterlevel = 1e-08, FILT = list(ON = FALSE,
fl = 1/30, fh = 7, type = "HP", proto = "BU"))
Arguments
TH |
list structure of seismic traces |
sel |
select which tracesin list to deconvolve |
inst |
index to instrument in Kal list for calibration and instrument response |
Kal |
list of instrument responses |
waterlevel |
waterlevel for low frequency division |
FILT |
filter output, after instrumentation |
Details
Instrument responses are lists of poles and zeros for each instrument defined.
Value
Same as input list with new traces representing velocity versus volts
