Bemerkung: 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 ³P0-³D1 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 5s² ¹S0 state in Hz m² / W
- the shift of the 5s5p ³P0 state in Hz m² / 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 5s² ¹S0 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 ³P0 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 configuration of the level
- the approximate transition wavelength

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 ³D1 - 5s5p ³P0 transition of 115.1662621 THz as a function of temperature. The columns contain
- the temperature in K
- the value of G for the 5s4d ³D1 - 5s5p ³P0 transition and the temperature given in the first column
