Muting
 
 These programs allow user defined muting of trace data.  Functionality
exists to perform first break muting under either time,velocity [mute] or
pickfile [bdmute] control. Surgical and polygonal muting are supported
[bdmute]. When working in tau-p your transform can be bounded using taumute.
When using pickfile input be aware that bdmute is indexed on sequential
record number and does not honor trace header indexing. To restore a
mute use [mute -R].
