Detailed Description

Function Documentation

mkAlphaS() [1/4]

AlphaS* LHAPDF::mkAlphaS

(

const Info &

info

)

Make an AlphaS object from an Info object.

The type and configuration of the returned AlphaS is chosen based on the PDF metadata Info object given as the argument.

Returns a 'new'ed AlphaS by pointer. Unless attached to a PDF, the caller is responsible for deletion of the created object.

mkAlphaS() [2/4]

AlphaS* LHAPDF::mkAlphaS	(	const std::string &	setname,
		size_t	member
	)

Make an AlphaS object for the specified PDF.

The type and configuration of the returned AlphaS is chosen based on the named PDFSet's nth member's metadata.

Returns a 'new'ed AlphaS by pointer. Unless attached to a PDF, the caller is responsible for deletion of the created object.

mkAlphaS() [3/4]

AlphaS* LHAPDF::mkAlphaS

(

const std::string &

setname_nmem

)

Create an AlphaS object for the given set name and member number as a single string

The format of the setname_nmem string is <setname>/<nmem> where <nmem> must be parseable as a positive integer. The / character is not permitted in set names due to clashes with Unix filesystem path syntax.

If no /<nmem> is given, the type and configuration of the returned AlphaS is chosen based on the named PDFSet's metadata, NOT the info of member number 0 as for similar methods. If there is a distinction and you specifically want the AlphaS for the central member rather than that specified for the set as a whole, make sure to include the "/0"!

Returns a 'new'ed AlphaS by pointer. Unless attached to a PDF, the caller is responsible for deletion of the created object.

mkAlphaS() [4/4]

AlphaS* LHAPDF::mkAlphaS

(

int

lhaid

)

Make an AlphaS object for the specified PDF.

The type and configuration of the returned AlphaS is chosen based on the numbered PDF's metadata.

Returns a 'new'ed AlphaS by pointer. Unless attached to a PDF, the caller is responsible for deletion of the created object.

mkBareAlphaS()

AlphaS* LHAPDF::mkBareAlphaS

(

const std::string &

type

)

Make an AlphaS object of the requested type without a PDF reference.

No values are initialised and have to be configured by the caller.

The caller is responsible for deletion of the created object.
