Description of the individual files:
The files 'Approximation_G(n)_Sr.dat' and 'Approximation_G(n)_Yb.dat' contain data shown in Fig. 1 of the manuscript. The columns give
	the order n up to which the approximative solution Eq. 4 of the manuscript has been calculated
	the approximative solution G_n(y) for y = 18.4 and 34.5 corresponding to T = 300 K and the energetically lowest transitions ^3P_0-^3D_1 in strontium and ytterbium, respectively
	the fractional deviation of G_n(y) from the full integral

The file 'levelshift.dat' gives the shift of the strontium clock states due to the electric dipole interaction with electromagnetic radiation. The data is for illustration only. The columns give
	the wavelength of the radiation in nm
	the shift of the 5s^2 ^1S_0 state in Hz m^2 / W
	the shift of the 5s5p ^3P_0 state in Hz m^2 / W

The file 'BBR_shift.dat' gives the temperature-dependent BBR shift for the strontium clock transition. The columns contain
	the temperature in Kelvin
	the total BBR shift in Hz
	the dynamic contribution to the BBR shift in Hz
	the fractional uncertainty of the static contribution to the BBR shift in 1E-19
	the fractional uncertainty of the dynamic contribution to the BBR shift in 1E-19
	the residuals of the parametrization of the dynamic contribution by Eqs. 6 & 7 of the manuscript in 1E-19

The file 'S_levels.dat' lists the levels that are connected to the 5s^2 ^1S_0 state (term energy 0 cm^-1) by dipole transitions and are used in the analysis (Tab. I of the paper). The columns contain
	the configuration of the level
	the approximate transition wavelength
	the Einstein A coefficient in 1/s
	the source of the Einstein coefficient

The file 'P_levels.dat' lists the levels that are connected to the 5s5p ^3P_ 0 state (term energy 14317.507 cm^-1) by dipole transitions and are used in the analysis (Tab. II of the paper). The columns contain

The file 'G(3D1_T).dat' gives the values of the function G defined in Eq. 3 of the manuscript for the transition frequency of the 5s4d ^3D_1 - 5s5p ^3P_0 transition of 115.1662621 THz as a function of temperature. The columns contain
	the temperature in K
	the value of G for the 5s4d ^3D_1 - 5s5p ^3P_0 transition and the temperature given in the first column
