CalRecon Data

Diagram of Proposed CalRecon TDS Architecture

• ... can be found here

Prototype Definition of the CalParams Class

• Prototype class found here
• Intended to provide a single interface to all the basic energy reconstruction parameters:
  • Energy
  • The reconstructed energy centroid (cluster position)
  • The axis of the energy flow (cluster axis)
  • And the errors assigned to these
    • For energy: a number
    • For centroid and axis: two 3x3 error matrices
• Is a subclass of the main recon output classes

Prototype Definition of the CalCluster Class

• Prototype class found here
• This replaces the current CalCluster class, splitting out the corrected energy information that was formerly contained in CalCluster
• Otherwise, basically a reformatting of what was there:
  • The layer by layer information formerly stored in three std::vectors is now replaced by a subclass (CalClusterLayerData). CalCluster now derives from a std::vector of these objects making them directly accessible externally without having to provide access methods
    • Example:

       CalClusterLayerData lyrData = calCluster[layer]; 

  • The energy, cluster centroid and cluster axis information is stored in an internal CalParams object.
    • Now includes errors on these quantities
    • But not yet filled with "real" values
• New things include:
  • CalCluster is a "ContainedObject"
    • typedef's are provided to defined the TDS Object container (CalClusterCol) which will store the clusters in the TDS
  • A relational table will relate CalClusters to the CalXtalRecObjects which comprise them
    • typedef's are provided to define this table
• A comment on the layer by layer data
  • Attempted to preserve the "old" system of an entry for each layer in the Cal, whether data existed or not. Unfortunately, one downside is the need to #define a default value of 8 so the constructor will be sure to create a vector of size 8 for the CalClusterLayerData objects...
  • A possible future solution would be to include a Cal identifier in the CalClusterLayerData object and then only keep non-zero entries
  • Other possibilities?
• Something forgotten: a status bit word...

Prototype Definition of the CalCorToolResult Class

• Prototype class found here
• DISCLAIMER: bare bones version, no attempt yet to add mechanism for storing correction tool dependent information

Prototype Definition of the CalEventEnergy Class

• Prototype class found here
• Contains the basic energy reconstruction parameters
• Is really useful
