bbal - BSU program scales two data sets so that they have the same MAV (C-Language Version)
bbal [ -h | infile1 | infile2 | iopt ]
Basic Seismic Utilities (BSU) computes the Mean Absolute Value (MAV) of two data sets on either a trace by trace, or profile basis. Then, each data set is rescaled to the average of the two data set MAV’s. C-Language Version.
Options
|
-h |
Online help giving details on command line arguments |
infile1 (char)
Input file name
infile2 (char)
Input file name
iopt (int)
Switch to choose profile or trace mode.
0=profile mode
1=trace mode
NOTE:
If invoked with no options, will prompt user for input
parameters.
EXAMPLE:
bbal w001.seg w002.seg 1
File the MAV for each trace in each data set is computed (say MAV1 and MAV2 for the i_th trace) Then each trace is rescaled so that their respective new MAV values become (MAV1+MAV2)/2.
bbalxxxx.seg
named according to convention (first 4char bbal, the next 4char are the first 4char of the input file name, suffix .seg). There will be two of these data sets, and one must take care with the names of the input (SEE BUGS BELOW).
standard output
produces a progress bar
bbalxxxx.lst
Echo check of input parameters in listing file.
bhelp(1), mav(3)
no known bugs, BUT, the file name convention can be a problem if the first 4 characters of each data name are the same. For example, if one were to run the following:
bbal twav0001.seg twav0002.seg 1
Then the output data sets would both have the same name, with one being written over with the other (ie. output name would be bbaltwav.seg for both).
