A trace representing the sum of all traces in therecord will be created within this time window and this summed tracewill be cross correlated with each trace in the same time window.tmax is the maximum time shift that will be allowed i.e. it crosscorrelateion lag times will only be allowed between (tmax) and (-tmax)and a maximum will be found between these lag times.Time shifts will be stored in trace header word 25.Convention: positive value = shift traces down negative value = shift traces upSuccessive applications of this module will improve final trace alignment.Similar to INSIGHT module 'trim'.DSI customized VSP processing softwarewritten by Kristen Beaty November, 1997</pre><HR><H3>Cross-Reference Information</H3>This function is called by<pre><UL><LI><A HREF = "../4.demos/demoproc.html">demoproc</A> ./demos/demoproc.m</LI><LI><A HREF = "../8.main/medirm.html">medirm</A> ./main/medirm.m</LI></UL></pre><HR>Produced by <A HREF = "http://www.nd.edu/Courses/kantor/matlab/mat2html">mat2html</A> on Wed Jun 14 15:21:32 Canada/Eastern 2000<BR>Cross-Directory links are: ON<BR></BODY>⌨️ 快捷键说明
