bmrk - BSU marks traces with a spike at time picks from headers
bmrk [ -h | infile | ipol | fscl ]
Basic Seismic Utilities (BSU) inserts spikes on seismic data to mark the pick times found in the headers. This program may be useful in quality control of first break picking, or to generate synthetic data based on the pick time. For example, one could take a data set with picks in the headers, zero the data (bkil), insert delta functions with bmrk, and then filter the data with bfil. An alternative to this program (if quality control of picks is the objective) is to time align the data on a time line using bshf.

Polarity of delta function to insert into the data traces. | ||

Scale factor to scale the delta function by. |
NOTE:
If invoked with no options, will prompt user for input
parameters.
EXAMPLE:
bmrk wave.seg +1 100.
Input file wave.seg has delta functions (scaled to amplitude=100.) inserted at the first break pick times which have already been inserted into the headers.
bmrkxxxx.seg
Named according to convention (first 4char bmrk, the next 4char are the first 4char of the input file name, suffix .seg)
standard output
produces a progress bar
bmrkxxxx.lst
echo check of input parameters.

No known bugs.
