Trigger Simu Test

Updated on Wed, 2007-11-28 14:27. Originally created by ahoffman on 2007-11-28 14:27.

I am trying to figure out why the trigger simulator only returns as 'good' a fraction of the events returned as 'good' by the online L2-gamma trigger.  Let me state that a different way...

Looking at the Gaussian Widths:

Updated on Mon, 2007-12-10 13:31. Originally created by rcorliss on 2007-12-04 11:41.

We now have the fitting algorithms working for both the LDA and the 2-D approach.  The results are plotted below, marking actual values in black, the 2D values in red, and the LDA values in blue.

Spill-over Events

Updated on Wed, 2007-12-12 11:50. Originally created by rcorliss on 2007-12-10 15:19.

It doesn't look like I can remove the spillover events from the training samples without drastically changing their content.  Now I just have to figure out what to do with them to keep the distribution sensible.

Below are x1 and x2 distributions for different eta bins. eta3 is always the larger of the two jet etas.

More on Raw BSMD ADC Distributions

As Will pointed out, you can't always say with 100% certainty whether a given module is showing banding structure just by looking at the raw ADC vs.
