bmix - BSU program MEAN mixes seismic data across the trace direction
bmix [ -h | infile | mix ]
Basic Seismic Utilities (BSU) mixes traces using the add and subtract trick for a box car operator. Double precision arithmatic is used for the accumulator. This program was designed for wavefield separation on time aligned data, so it does not taper in/out at the edges of the data set. Rather, it replicates mix/2 traces from the midpoint out to the end of the data. This is a MEAN mix, NOT a MEDIAN mix. For a median mix, use bmed.

The width of the box car mix operator (must be odd, and software makes sure it is). |
NOTE:
If invoked with no options, will prompt user for input
parameters.
EXAMPLE:
bmix bshfwave.seg 11
File bshfwave.seg is mixed with an 11 trace spatial mix operator.
bmixyyyy.seg
Output, mean mix data set. Named according to convention (first 4char bmix, the next 4char are the first 4char of the input file name, suffix .seg)
standard output
produces a progress bar
bmixyyyy.lst
