| + | * 5/24/2012: (kathrin) checked runs 694 (old decomp) and 697 (new decomp) taken on 05/22 | ||
| + | |||
| + | coincidences = s800 and gretina GGEB header with time stamps within 1000 ticks | ||
| + | s800 singles = missing gretina GGEB header and event | ||
| + | gretina singles = no s800 in this event | ||
| + | decomp fails = error in decomposition, "pad" of gretina struct is != 0 (I get errors 3 and 5 see below) | ||
| + | |||
| + | Run 694: | ||
| + | 172171 coincidences (94.4 %) | ||
| + | 10207 S800 singles (5.6 %) | ||
| + | 18 Gret singles (0.0 %) | ||
| + | 0 Decomp fails (0.0 %) | ||
| + | |||
| + | Run 697: | ||
| + | 97888 coincidences (91.2 %) | ||
| + | 9477 S800 singles (8.8 %) | ||
| + | 0 Gret singles (0.0 %) | ||
| + | 81 Decomp fails (0.1 %) | ||
| + | | ||
| + | decomp fails are included in the coincidences (since they have a valid time stamp), as error I get 3 and 5. | ||
| + | in both cases the event is completely empty (everything is zero) except for the crystal_id. | ||
| + | out of the 81 failures I have 54 error 3 (no net charge segments) and 27 times error 5 (bad chi^2) | ||
| + | | ||
| + | this test has to be repeated, to me it is completely unclear, why run 694 has again S800 problems (these were thought to be solved before) | ||
