DQ flag description

Algorithm 1: cosmic run.

Beside each subdir in the egamma web display described earlier, you will see three possible colors: Grey, Green, Red. Grey means that we do not have enough statistics so we are unable to make a decision. Green means that everything is fine. Red means that you have a problem somewhere.

To set the DQ flags we use the Not empty test(Histogram_Not_Empty). For each histo in a given subdir "X", we check the histograms are empty or not with respect to a reference histogram. If the histogram is empty, is will be Red, if not, it will be Green. And we are using "Simple summary" as a summary algorithm, which means:

- If the number of the empty histogram is larger than the not empty ones, the subdir "X" is set to Red.

- If the number of the empty histogram is smaller than (or equal to )the not empty ones. the subdir "X" is set to Green.

- The Grey is not likely to happen in this case. It will be Grey only at the start of a run when the histograms are not published.

TRELE(TRGAM) is Red, if there are more Red sub directories than green ones. TRELE(TRGAM) is Green, if there are less Red sub directories than green ones. TRELE(TRGAM) will be grey at the beginning of a run.

Algorithm 2: collision run.

Beside each subdir in the egamma web display described earlier, you will see three four colors: Grey, Green, Yellow, Red. Grey means that we do not have enough statistics so we are unable to make a decision. Green means that everything is fine. Red means that you have a problem somewhere. Yellow means that you are between Red and Green and you need to do some work to understand what is going on.

To set the DQ flags we use the Kolmogorov test (Max Diff). For each histo in a given subdir "X", we apply a Kolmogorov test with respect to a reference histogram. histogram. If the histogram can not pass low threshold of Kolmogorov test, is will be Red; if the histogram can pass the low threshold but can not pass the high threshold, it will be Yellow; If the histogram can pass the high threshold of Kolmogorov test, it will be Green. If there is not enough statistics to make the test, it will be Grey. And we are using "Simple summary" as a summary algorithm, which means:

- If the number of the green histogram is larger than (or equal to ) the number of yellow ones and green ones, the subdir "X" is set to Green.

- If the number of the yellow histogram is larger than the number of green ones and the red ones. the subdir "X" is set to Yellow.

- If the number of the red histogram is larger than the number of green ones and the yellow ones. the subdir "X" is set to Red.

- If all the histograms do not have enough statistics, the subdir "X" is set to Grey.

TRELE(TRGAM) is Red, if there are more Red sub directories than other ones. TRELE(TRGAM) is Green, if there more Green sub directories than other ones. TRELE(TRGAM) is Green, if there more(or same) Green sub directories than other ones. TRELE(TRGAM) will be grey if all the sub directories are grey.
