(note that the routine gives phierr as phierr(1,...) 
                and phierr(2,...) in order to incorporate Jackknife (eventually). 
                Currently phierr(1,...)=phierr(2,...). Note that phi + 2 phierr(1,...) and phi -2 
                phierr(2,...) will give 95% confidence bands for phi - only for err(1)&gt;=1
 Cerr  : error bars for coherency (only for Jackknife estimates)-only for err(1)=2</pre></div>
