Detailed Description

Physical constants (i.e. dimensioned values)

Public interface

Review Status

Prerequisite

Quantum

Etymology

A QC is based on the Quantum and C (constants) class

Synopsis

QC:name will produce a Quantity (Quantum<Double>) value consisting of a value and a unit. See the Quantum class for possibilities of manipulating quanta. tQuantum will give a list of the currently available constants

Example

To obtain the velocity of light in pc/a, use:

#include <casacore/casa/Quanta.h>

Double vel_pcpy = (C::c).convert("pc/a").getValue();

The following constants are defined as public data members of class QC.

Caution: The following public data member documentation is currently extracted by hand, and thus could be out of date if this documentation was not updated when the class was modified;

// vel of light
static Quantum<Double> c;
// Gravitational constant
static Quantum<Double> G;
// Planck
static Quantum<Double> h;
// HI line
static Quantum<Double> HI;
// Gas constant
static Quantum<Double> R;
// Avogadro
static Quantum<Double> NA;
// electron charge
static Quantum<Double> e;
// proton mass
static Quantum<Double> mp;
// mp/me
static Quantum<Double> mp_me;
// permeability vacuum
static Quantum<Double> mu0;
// permittivity vacuum
static Quantum<Double> epsilon0;
// Boltzmann
static Quantum<Double> k;
// Faraday
static Quantum<Double> F;
// mass electron
static Quantum<Double> me;
// radius electron
static Quantum<Double> re;
// Bohr's radius
static Quantum<Double> a0;
// Solar radius
static Quantum<Double> R0;
// IAU Gaussian grav. const **2
static Quantum<Double> k2;
// quarter turn = 90 degrees = pi/2 radians
static Quantum<Double> qTurn;
// half turn = 180 degrees = pi radians
static Quantum<Double> hTurn;
// full turn = 360 degrees = 2pi radians
static Quantum<Double> fTurn;

Motivation

Physical constants should be known with their proper dimensions
