We report on further development of the 'StandardPhysicalConstants' package, presented at IMS2001. We address these issues: package structure; current status of the physical constant database; data sources; current data collection and data structure; the main modules of the data management system; the first version of "error propagator"; usage examples in calculations for high precision tests of physics theories. We also indicate future developments of the basic package.
The `PhysicalConstantValues` Package
This package is meant for an easy access to widely used physical, astrophysical and physicochemical constants, which are of interest to specialists in high energy physics, particle physics, astrophysics and cosmology. This package can be considered as an extention of the standard package Miscellaneous`PhysicalConstants` of the Mathematica system, both by the number of constants and number of their numerical characteristics. The current version of the package database contains 112 constants.
The main sources of data included in the package database are 1) P.J.Mohr, B.N.Taylor, CODATA Recommended Values of the Fundamental Physical Constants: 2002. http://physics.nist.gov/constants; 2) K.Hagiwara et al. Review of Particle Physics [Particle Data Group], Phys. Rev. D66, 1 (2002); http://pdg.lbl.gov.
The more detailed description of the previous package version, which does not have any fundamental differences from current version, can be found in the work by Larin V.N. The 'PhysicalConstantValues' Package for Mathematica System. IHEP Preprint 2002-40.- Protvino, 2002 (in Russian). The work can be found at http://dbserv.ihep.su/~pubs/prep2002/ps/2002-40.pdf
Dec 13, 2004: The databases in the both StandardPhysicalConstants and PhysicalConstantValues was updated according to new CODATA-2002 and PDG-2004 data.
