Detailed Description
A class for mixing pi0 candidates.This class takes as input points found using StEEmcIUPointMaker or a derivative class. We then loop over all possible pairs of points to find pi0 (eta) --> gamma gamma candidates.
Points from each event are stored in a E_T ranked pool, which we then mix to form combinatoric background candidates. In the future we may create a separate maker for mixed events.
The code allows two cuts:
- Trigger list -- the user may specify a list of triggers to process
- Sector limits -- by default, points are mixed if in the same sector. The user may specify other sector-wise limits.

| void StEEmcIUMixMaker::sector | ( | Int_t | sector | ) | [inline] |

sector An EEmc sector, [0,11]

| void StEEmcIUMixMaker::setTrigMode | ( | Int_t | m | ) | [inline] |
Sets the trigger mode for combinatoric background mixing. Points will be saved from event-to-event in a "pool". By default, any or all points in an event can get into the pool (default=0, minbias). If high-tower is selected, we do not allow points beneath the highest tower in the event (the triggered tower) to enter the pool. If jet-patch is selected... well, we don't know how to handle this yet so it behaves like minbias.
- Parameters:
-
m,: 0=minbias, 1=high-tower, 2=jet patch

| void StEEmcIUMixMaker::trigger | ( | Int_t | trigger | ) | [inline] |

- Parameters:
