# Atomic masses are based on:
#
# Meija, J., Coplen, T., Berglund, M., et al. (2016). Atomic weights of
# the elements 2013 (IUPAC Technical Report). Pure and Applied Chemistry,
# 88(3), pp. 265-291. Retrieved 30 Nov. 2016,
# from doi:10.1515/pac-2015-0305
#
# Standard atomic weights are taken from Table 1: "Standard atomic weights
# 2013", with the uncertainties ignored.
# For hydrogen, helium, boron, carbon, nitrogen, oxygen, magnesium, silicon,
# sulfur, chlorine, bromine and thallium, where the weights are given as a
# range the "conventional" weights are taken from Table 3 and the ranges are
# given in the comments.
# The mass of the most stable isotope (in Table 4) is used for elements
# where there the element has no stable isotopes (to avoid NaNs): Tc, Pm,
# Po, At, Rn, Fr, Ra, Ac, everything after Np

# This data is from Ashcroft and Mermin.
# Most constants are listed in periodic table, inside front cover.
# Reference states that have a non-trivial basis have a 'basis' key.
# If the basis is None, it means it has a basis but we have not tabulated it.
# For basis of RHL systems (represented here as basis_x) see page 127.
# For TET systems see page 127, too.
