Detailed Description

Miscellaneous math functions.

Function Documentation

csection()

csection

(

filename

)

Extract cross-section from gzipped LHE file.

WARNING: This function does not work!

Todo:

remove or replace by more useful function

Parameters

filename

name of input file

Definition at line 20 of file func.py.

lint()

lint	(		target_dz,
			num_electrons,
			density = 6.306e-14
	)

Calculate integrated luminosity.

Parameters

target_dz	target thickness in cm
num_electrons	number of electrons in bunch
density	1/(cm*pb), default value is for tungsten

Returns

integrated luminosity in 1/pb

Definition at line 9 of file func.py.

mu()

mu	(		filename,
			target_dz,
			num_electrons
	)

Calculate mu = number of events per bunch.

WARNING: This function does not work properly because csection() is broken!

Parameters

filename	name of input LHE input file containing cross section
target_dz	target thickness in cm
num_electrons	number of electrons in bunch

Returns

number of events per bunch (L_int[1/pb] * xsec[pb])

Definition at line 44 of file func.py.

nbunches()

nbunches	(		filename,
			target_dz,
			num_electrons
	)

Get the approximate number of beam bunches represented by an LHE file from its event count.

Parameters

filename	name of input LHE file
target_dz	target thickness in cm
num_electrons	number of electrons in bunch

Definition at line 84 of file func.py.

nevents()

nevents	(		filename,
			confirm = False
	)

Read number of events in file from LHE header and optionally confirm by counting <event> blocks.

Parameters

filename	name of input LHE file
confirm	set to True to confirm number of events

Definition at line 57 of file func.py.
