Overview

The CalDetDST package was designed to create a TTree to hold many characteristics of CalDet beam events. There are three versions of the CalDetDST. The first, created by running the job module UberModule, contains derived event quantities, limited hit information, as well as the results of the Standard Reconstruction. The second, created by running the UberModuleLite job module was designed to provide quick feedback at the time of data taking. Trees created using UberModuleLite hold a subset of the data available in the UberModule tree variety. The final version, created by running the UberDST job module is no longer supported. The TTree that results from running UberModule is called ``snarltree'', and each row in snarltree contains a class called UberRecord. UberRecord derives from the standard offline ntuple class, and as such, each row in the tree is accompanied by a header called UberRecHeader. The methods that extract data from the header are listed in a table below. The beam momentum stored in the header class is read from the database table CALDETBEAMMOMENTUM, a supplemental database table that was created by hand; it is not obtained from the run comments. UberRecords hold another class called UberHit, which holds information specific to each of the hits in the event. The data stored in the UberHit and UberRecord are given in tables below.

Input/Output

Input Objects

UberModule needs the following objects:

Output Objects

Produces a TTree output file

Database Access

No direct dependence, but objects needed to make the DST need the database.

Configuring & Running

No configuration parameters. See uber-all.C for an example job macro.
