Detailed Description

main(...) function for the qwparity executable

Function Documentation

main()

Int_t main	(	Int_t	argc,
		Char_t *	argv[] )

Enable implicit multi-threading in e.g. TTree::Fill

Define the command line options

Define additional command line arguments and the configuration filename, and we define the options that can be used in them (using QwOptions).

Without anything, print usage

First, fill the search paths for the parameter files; this sets a static variable within the QwParameterFile class which will be used by all instances. The "scratch" directory should be first.

Load command line options for the histogram/tree helper class

Setup screen and file logging

Create the event buffer

Create the database connection

Start loop over all runs

Begin processing for the first run

Set the current event number for parameter file lookup

Create an EPICS event

Load the detectors from file

Create event-based correction subsystem

Create the helicity pattern

Create the event ring with the subsystem array

Create the data handler arrays

Create the burst sum

Create the running sum

Start loop over events
