Purpose

This web page is for experts who wants to check the L1 Trigger Object Definitions by oneself.

Command

You can print the definitions (the one was loaded in ir2) by running the following command at a prompt:
CfgUtils -v ListKeys Dct L1DZpdDecisionModLut:Default last  (for ZPD objects)
CfgUtils -v ListKeys Emt L1EmtAxRecord:AxConfig last  (for EMT objects)

Note:

Understanding the output

The ZPD objects

Here is the example output from running:  "CfgUtils -v ListKeys Dct L1DZpdDecisionModLut:Default last". We'll ignore the ascii-art part here.

The three blocks are same information given in different units. Some of interesting variables:

A little more detail explaination on rho and pT cuts:
For bit 0 (Z), ptMin was 200 MeV and rhoMin and rhoMax was -93 and 93, respectively. From here we get 'rho=93' is same as 'pT=200 MeV'. In the same way, from bit 3 (Z'), we get 'rho=23' is same as 'pT=800 MeV'. For bit 4 (Zk), rhoMin is -93 and rhoMax is 23. So we translate this into -200 MeV and +800 MeV pT cuts. The sign matches with the charge of tracks. Thus, they correspond to 800 MeV pT for positively charged tracks and 200 MeV pT for negatively charged tracks.

The EMT objects

Here is the example output from running:  "CfgUtils -v ListKeys Emt L1EmtAxRecord:AxConfig last".

Each of the 40 rawData[i]'s coresponds to one of the 40 phi sums of EMT towers. The information for EMT objects are same in all of the entries. Some of interesting variables:

Here is the example output from running:  "CfgUtils -v ListKeys Emt L1EmtFcxRecord:FcxConfig last".

Here is the example output from running:  "CfgUtils -v ListKeys Emt L1EmtFxRecord:FxConfig last".
