Table 1:

Note 1. The quotients of the measured intensity ratios and theoretical for the six Si I spectral lines from the resonance transition. The transition probabilities (A) and statistical weights (g) are taken from NIST (2009). Every cell contains quotient Q_p,q calculated for particular pair of spectral lines p and q, measured at the same temperature. The first group of three lines (250.690 nm, 251.432 nm, 251.611 nm) is recorded at T=15 000 K, the second group (251.920 nm, 252.411 nm, 252.851 nm) is recorded at T=12 500 K.
