Hi all,<br><br>In the cooking that I did yesterday for the DC_SWAP test I did changed the fitting parameters <br>of the DC histograms to be similar to the dc3 program. This test includes the whole files of a <br>run 61695. The new fit results of the first ten files of this run can be compared with the previous "pass0_v1" cooking of the same run. You can access the last and new fit results on the following <br>
link: <a href="http://www.jlab.org/Hall-B/secure/eg6/cooking/online_sql/mon_r61695.html">http://www.jlab.org/Hall-B/secure/eg6/cooking/online_sql/mon_r61695.html</a><br>The two tables on this link stand for: old cooking "pass0_v1" and new cooking "pass0_dcs3".<br>
However, the x-axis of all pictures are showing a file's extension instead of a run number since <br>the comparison is including just one run "61695".<br><br>Best regards,<br><br>Lamiaa<br><br clear="all">************************************************************<br>

Hi Seema,<br>
<br>
Thanks for looking into this. I do not think initial<br>
setting of parameters will effect much. In user_ana<br>
"B" in the fitting option and "0" for number of parameters<br>
means that initial value of parameters are recalculated.<br>
The straight forward check is to fit the same histogram<br>
with both settings and see if there is a difference.<br>
You can take one of histograms from cooked monitoring<br>
histograms and fit with settings in dc3.<br>
