Detailed Description

A cluster maker for the EEMC.

This class produces clusters of EEMC towers, pre- and postshower elements and smd strips.

Weihong He

Tower, pre- and postshower algorithm

The clustering-algorithm used for tower clusters (as well as preshower and postshower clusters) is the Minesweeper algorithm originally developed by Jan Balewski.

The SMD Algorithm

The SMD clustering algorithm starts by finding all strips which exceed a user-specified seed threshold. These strips are sorted by energy, and we work from the most energetic seed to the least energetic seed.

Strips adjacent to the smd seed are added to the cluster and removed from the pool of seed strips. The number of adjacent strips added is specified by the user in the setMaxExtent(max) method and the default strip number is set to 3 to both sides around a seed strip.

Once a cluster is identified, the seed threshold is raised in the vicinity of that cluster, including a special floor setting described below. For details, see buildSmdClusters().

SMD Cluster Cuts

In order to form a cluster, we require a minimum of three smd strips. Fewer strips suggests a MIP, although low-energy EM showers (<~ 1 GeV) can deposit energy in only two consecutive smd strips.

The user may also specify the suppress() option for the cluster maker. When this option is used, the two smd strips adjacent to the cluster are removed from the pool of smd seed strips. This reduces the effects of false cluster splitting, i.e. where a fluctuation in the size of the EM shower combined with the fixed size of the cluster leads to the formation of a false smd cluster.

For Monte Carlo data, you need to switch on #define MonteCarloS For real and pythia data, you need to switch off #define MonteCarloS

Constructor & Destructor Documentation

StEEmcIUClusterMaker::StEEmcIUClusterMaker ( const Char_t *  name = "mEEclusters")

by default, do not populate the StEmcClusterCollection

default, do not supress seeds adjacent to clusters

each cluster (tower, pre/post, smd) are assigned a unique id in the order in which they are collected

Set default seed energies

Initialize storage banks for tower and SMD clusters. Both will be stored sector-wise and layer-wise.

Tower clusters are stored according to the sector in which we find their seed tower.

Layers: T=0, P=1, Q=2, R=3 / Planes: U=0, V=1

mTowerClusters[sector][layer] returns vector of tower clusters mSmdClusters[sector][plane] returns vector of SMD clusters

Member Function Documentation

Bool_t StEEmcIUClusterMaker::buildSmdClusters ( )

Constructs smd clusters.

Loop over all sectors

Loop over all planes

Try to cut down on noice around identified gammas

Energy of all strips in plane

Get list of strips

Sort by energy

Order in descending energy

Copy energy of all hit strips into an array

We'll flag each seed strip

Iterate over strips and find seeds

We always ignore the corners of the planes

Verify that this is a good strip

Verify that this strip exceeds the floor by the specified seed threshold. If not, punt

Flag this as a seed strip

LOOSE_CUTS is an adhoc shower shape, where we try to suppress clusters if they are likely a fluctuation in the shower profile of an EM shower

Set a "floor" around this strip

Within +/- 2 strips, find no other seeds

Within +/- 4 strips, Floor is 20 or 40% of seed

Within +/- 10 strips, Floor i 10 or 20% of seed

Within +/- 20 strips, floor is 5% of seed

Now for each seed strip, add all contiguous, adjacent SMD strips out to +/- 3 strips on either side. Continuity is broken if strip falls below Nsigma threshold and is not marked as dead.

Verify that this seed is not owned by another cluster

This seed is now the property of a cluster

Create our cluster

And give it the strip

Now go +/- 3 strips on either side and add them to the cluster, respecting continuity etc...

Get the strip

Mark this strip as owned

Add to cluster

Get the strip

Mark this strip as owned

Add to cluster

Push the cluster into our storage vector

Bool_t StEEmcIUClusterMaker::buildTowerClusters ( )

Constructs tower clusters.

Current algo only populates tower clusters, using Jan's "minesweeper" algorithm (apologies to Bill Gates).

Loop over layers to go here... maybe above init of weights

Weights for dividing energy of towers among the tower-only clusters, like Jan's algorithm.

Temp storage for clusters

Get list of towers

Order according to energy (STL sort is fast, N log(N))

Order descending in energy

Find the last tower which exceeds see threshold (actually, "last" will be the first tower below the seed threshold).

store seed towers by layer, sector <<< this breaks, gives an "abort", which I assume means that we're trying to push a tower into a nonexistant vector... did I maybe get the order wrong???

We have run out of seeds here

This seed tower is adjacent to another seed tower and will be clustered with that one. No incrementation for now. (Future, we may allow this to be a seed if there's an SMD response beneath it, then use tower-sharing shape to divide...)

loop over neighboring towers and increment weight for this tower with the energy of the seed tower

Loop over towers again

We've run out of seeds

If the weight for this tower has been incremented, then it's adjacent to a more energetic tower and already is clustered with it.

set momentum and a unique key

void StEEmcIUClusterMaker::fillStEvent ( )

Fills StEvent cluster collections if the option is selected.

First the eemc tower clusters

If we found clusters, create a cluster collection for this detector. Otherwise, nullify the cluster collection, otherwise we run into an assert somewhere out in "STAR" land... or maybe not,... no comments in barrel virtual finder...

Obtain the cluster collection from the detector, and prepare to fill it. If it doesn't exist, create it.

Loop over all EEMC sectors and fill collection

Loop over all clusters in this sector

for some reason, this code doesn't work when I call StEEmcIUCluster::stemc(), but works just fine here....

association between StEmcCluster and my class

now set the collection in the detector

Next the pre and postshower clusters

Loop over all EEMC sectors and fill collection

Loop over PQR

Loop over all clusters in this sector //and layer
