0003 #
0004 # Modules for smearing 4-vector's angles of Objects
0005 #
0006 # Parameters:
0007 # - InputTag movedObject:
0008 #   Specify object to smear.
0009 #   Object type should correspond to module (e.g. Electron in module ElectronSpatialResolution)
0010 # - bool useDefaultInitialResolutions :
0011 #   Objects contain individual 4-vector resolutions (in terms of Et, theta/eta, phi).
0012 #   Set this to "true" if these should be used to compute initial resolutions for the smearing.
0013 # - bool usePolarTheta:
0014 #   Switch to specify, if eta or rather theta is used for the polar angle smearing.
0015 #   Set this to "true" to smear theta or to "false" to smear eta.
0016 # - double initialResolutionPolar:
0017 #   Initial resolution (in radiants for theta) to be used for the eta/theta smearing.
0018 #   Is given as absolute value only, since factors make no sense for angles.
0019 #   Overwritten, if 'useDefaultInitialResolution' is "true".
0020 # - double worsenResolutionPolar:
0021 #   Used to calculate the final resolution (after smearing) from the initial resolution.
0022 #   The angle is smeared with a Gaussion of
0023 #   mu    = angle and
0024 #   sigma = sqrt(finalRes^2-iniRes^2).
0025 # - bool worsenResolutionPolarByFactor:
0026 #   Flags the usage mode of 'worsenResolutionPolar' (how the final resolution is calculated from the initial one)
0027 # - double initialResolutionPhi, double worsenResolutionPhi and bool worsenResolutionPhiByFactor:
0028 #   Accordingly...
0029 #
0030 # Examples:
0031 #
0032 # Remarks:
0033 # - To switch off angular smearing, use (worsenResolutionPolar=0.) resp. (worsenResolutionPhi=0.)
0034 # - All numeric values are protected from "meaninglessness" by the usage of absolute values only.
0035 # - In the standard sequence at the bottom of this file, Taus are commented.
0036 # - Keep polar smearing switched off for MET objects!!! ;-)
