sfricker1 implements 1-D convolution with the Ricker wavelet.

The following example from rsf/rsf/wedge shows convolution modeling with a wedge model using sfricker1.

The convolution is implemented in the frequency domain, where the Ricker wavelet takes the form
$$F(\omega )=\frac{{\omega }^2}{{\omega }_0^2}\exp (-\frac{{\omega }^2}{{\omega }_0^2})$$
The peak frequency ${\omega }_0$ can be specified either in hertz (with frequency= parameter) as a fraction of the Nyquist frequency (with freq= parameter). Optionally, it is possible to combine the Ricker wavelet with a half-order derivative filter using deriv=y.
