sfpow multiplies the input data by a gain function of the form
$$G(x_1,x_2,\dots ,x_n)=x_1^{p_1}{x}_2^{p_2}\cdots x_n^{p_n}$$
The powers $p_1,p_2,\dots ,p_n$ are given by pow1=, pow2=, etc. parameters.

For backward compatibility, sftpow tpow= is an alias for sfpow pow1=.

The following example from geo391/hw1/tpow shows an application of sfpow pow1=2 *to a shot gather. The gain of *pow1=2 for seismic data was advocated by Jon Claerbout.

To estimate an appropriate power gain from the data, you can try sffpow.
