create synthetics

command: CREATE <type> <dt> <length> <amplitude>[<p1>[...<pN>]]

Creates a synthetic trace. There exist different types of traces which can be created (see parameter <type>).

parameters

• <type> parameter type: string
  Type of synthetic trace to be created. Valid parameters are:
  • SPIKE - spike trace, spike is positioned at <p1> seconds (time axis)
  • GAUSS - gauss peak at position <p1> seconds, <p2> specifies width
  • EXP - (one sided) exponential peak at <p1> seconds, <p2> = decay
  • SHARP - explosive point source at position <p1>, formula is g(t) = exp( -<p2>*(t-<p1>) * sin(<p3>*(t-<p1>))/<p3>
  • RANDOM - random trace

• <dt> parameter type: real
  Sample distance of trace.

• <length> parameter type: real
  Length of trace in seconds.

• <amplitude> parameter type: real
  Maximum amplitude of trace.
