Detailed Description

AnitaGeomTool – The ANITA Geometry Tool.

This is a utility class of useful thingies that can be used for some of the standard conversions that are needed in ANITA analysis. Some of the functions are static and can be called via AnitaGeomTool::functionName(), others require the user to get an instance of the AnitaGeomTool first using AnitaGeomTool *myGeomTool = AnitaGeomTool::Instance()

Member Function Documentation

void AnitaGeomTool::fillAntPositionsFromPrioritizerdConfig

(

)

Used for evaluating ANITA-3 Prioritizerd performance.

Use the geometrical information from he ANITA-3 Prioritizerd, from feed position numbers.

Definition at line 214 of file AnitaGeomTool.cxx.

Double_t AnitaGeomTool::getDirectionWrtNorth	(	Int_t	phi,
		Double_t	heading
	)

Get direction that a phi sector is pointing wrt north. Also takes heading as a input.

< Heading increases clockwise but phi-sector numbers increase anticlockwise, hence -ve sign.

Definition at line 765 of file AnitaGeomTool.cxx.

AnitaGeomTool * AnitaGeomTool::Instance ( int  anita_version = 0 )

static

Instance generator. If version_number == 0, uses AnitaVersion::get();.

Generates an instance of AnitaGeomTool, required for non-static functions.
