bequ - BSU program scales data by L2 norm or Peak Absolute Value (C-Language Version)
bequ [ -h | infile | tmin | tmax | normsel ]
Basic Seismic Utilities (BSU) trace equalizes seismic traces by either the trace L2 norm, or by the Peak Absolute Value. Due to backward compatibility needs, the "normsel" parameter is not prompted for in the event that the program is run in the interactive mode. Default is L2 norm. To invoke Peak Absolute Value scaling, you must enter this parameter on the command line. C-Language Version.

First argument is usually the input file name |
tmin (float)
Minimum time to start L2 norm computation (L2 is computed on a subset of the full trace, but applied to the entire trace.
tmax (float)
Maximum time to end L2 norm computation (L2 is computed on a subset of the full trace, but applied to the entire trace.
normsel (int)
Switch to select type of bsegy output.
0=Peak Absolute Value
2=L2 norm computed over interval [tmin, tmax]
NOTE:
If invoked with no options, will prompt user for input
parameters.
EXAMPLE:
bequ w001.seg .0 .5
File w001.seg is processed by bequ. The L2 norm is calculated only for the portion of the trace from 0 to 0.5 seconds.
bequxxxx.seg
named according to convention (first 4char bequ, the next 4char are the first 4char of the input file name, suffix .seg)
standard output
produces a progress bar
bequxxxx.lst
Echo check of input parameters in listing file.
