How to get the Level 3 paths and triggers in each stream


Unfortunately, what paths feed a given stream (even what paths exist) is very dependent on what trigger table is used, so there is no generic way of telling what paths are in what stream. This information can, however, be found on a run-by-run or trigger table-by-trigger table basis.

For a given run:

  1. Go to the CDF Run 2 database browser.
  2. Select "Triggers and Filters" in the first drop-down box and hit Submit request.
  3. Select "TF: Triggers and Bits" in the first drop-down box, and submit request.
  4. Select "Run Number" in the first drop-down box; enter the run number in the following text area; choose "Physics Table (3 of 7)" in the following drop-down box; and choose "Trigger (6 of 8)" in the drop-down box after that. (This will give you the name of the trigger table as well as the L3 info.) Submit request.
  5. You have your listing. The first table is the Level 1 and 2 information for the trigger table. The Level 3 information is organized by dataset. Look at the end of the dataset description for the stream it goes to: for example, Dataset Bias_April36x36_v-7 BIAS_APRIL36x36/StreamG goes to Stream G.

For a given trigger table:

  1. Go to the CDF Run 2 database browser.
  2. Select "Triggers and Filters" in the first drop-down box and hit Submit request.
  3. Select "TF: Triggers and Bits" in the first drop-down box, and submit request.
  4. Select "Physics Table (name_v-tag)" in the first drop-down box; enter the name of the table in the following text area; choose "Data set (4 of 7)" in the following drop-down box; and choose "Trigger (6 of 8)" in the drop-down box after that. Submit request.
  5. You have your listing; it is organized by dataset. Look at the end of the dataset description for the stream it goes to: for example, Dataset Bias_April36x36_v-7 BIAS_APRIL36x36/StreamG goes to Stream G.
