Detailed Description

Pede.

Implements only very basic PEDE functionality. Performs local and global fits. Features:

• fix parameters
• apply (linear equality) constraints
• reject bad records (based on Chi2 or failure of local fit)

Member Function Documentation

addBinaryFile()

def tinypede.Pede.addBinaryFile	(		self,
			binaryFileName,
			maxRec = 1000000,
			fileType = 'C'
	)

Add binary file.

Add C (default) or Fortran type binary file to list of files. Optionally specify maximum number of records to read from that file.

Parameters

[in]	binaryFileName	name of MP-II binary file
[in]	maxRec	maximal number of records
[in]	fileType	'C' or 'F'ortran type

Definition at line 267 of file tinypede.py.

References tinypede.Pede.__binaryFiles.

addConstraints()

def tinypede.Pede.addConstraints	(		self,
			textFile
	)

Add constraints.

Add (linear equality) constraints from text file. Accept only constraints with at least one variable parameter. Assume zero r.h.s. (C*p=0).

Parameters

[in]

textFile

file name (text file with constraints)

construct()

def tinypede.Pede.construct	(		self,
			chi2Factor = 50.
	)

Construct linear equation system.

Perform local fits, reject bad records (local fit failed) and records with too large Chi2(ndf) and build up global matrix and vector.

Parameters

[in]

chi2Factor

reject local fits with prob(chi2/chi2Factor,ndf) < 0.0027

defineParameters()

def tinypede.Pede.defineParameters	(		self,
			entriesCut = 25,
			fixedPar = []
	)

Define Parameters.

Read all binary files to get list of all global parameters. Apply (minimum number of) entries cut and list of fixed parameters to get list of free/variable parameters.

Parameters

[in]	entriesCut	entries cut
[in]	fixedPar	fixed parameters (labels)

(

(

Solve linear equation system.

Solve linear equation system (global fit) and print results.
