The main tree T has some branches that sound like they're what I'm<br>

Once I updated the DB with the correct slot and crate locations for the TDCs, my histos look as expected. <br>
<br>**Brad -- These changes to the DB for the scintillators have <not> been implemented to the d2n analyzer just yet... I want to finish my check/fine tuning of the calibration of the scintillators before I forward along the changes for the DB.<br>

Does anyone have/know of any documentation where I can just get a list of<br>
what variables exist and what they mean, for LHRS and/or for BBITE??<br>
Suppose I just *think* I'm looking at the right variables ... is there any<br>
way to pick the right ones apart from (1) trial and error or (2) pestering<br>
other people for their code? Some variables obviously follow conventions,<br>
e.g. for particular shower blocks, but what if you don't know the<br>
convention for the particular X you're looking for?<br></blockquote><div><br>I have this page bookmarked in firefox and is usually open almost all day as a reference: <br><br><a href="http://hallaweb.jlab.org/root/doc/variables.html">http://hallaweb.jlab.org/root/doc/variables.html</a><br>
<br>This is a list of all the Hall A Analyzer variables for LHRS. I don't know if one exists for BigBite, unfortunately.<br><br> I hope this helps!<br><br><br>Dave<br></div></div><br clear="all"><br>-- <br>-----------------------------------------------------------<br>
