Could you rerun your eloss tests as well?<br>
Thanks,...Andy<br>

Folks,<br>
when I corrected the target position based on our reconstructed data (-0.8cm upstream from the drawing), I used a simple loop to correct all positions ... BUT this loop was executed every time the routine was called (i.e. as Eugene pointed out: the target moved slowly backward out of CLAS - which obviously did not happen).<br>
I corrected this stupid mistake ... <br>
<br>
Please redo the eloss shared lib again (the code in /home/clasg14 is corrected):<br>
cd rootbeer2.1<br>
make eloss_clean<br>
make eloss<br>
<br>
And Dao and Haiyun, please do your eloss tests again. <br>
<br>
Franz <br>
