bmed - BSU program median mixes seismic data across the trace direction
bmed [ -h | infile | mix ]
Basic Seismic Utilities (BSU) mixes traces using a median mix. Current version is limited to a 21 trace median mix, but this can be increased by modifying the source code and recompiling. Designed for wavefield separation on time aligned data, the code 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. Note, this is a MEDIAN mix. If you want to use the MEAN mix, then you will want to run bmix instead.

NOTE:
If invoked with no options, will prompt user for input

EXAMPLE:
bmed bshfwave.seg 11
File bshfwave.seg is mixed with an 11 trace spatial median mix operator.
bmedyyyy.seg
Output, median mixed data set. Named according to convention (first 4char bmed, the next 4char are the first 4char of the input file name, suffix .seg)
standard output
produces a progress bar
