Our measured Stark FWHM ($W_{\rm m}$) and shift ($d_{\rm m}$) values at various electron temperatures (T) and densities (N) together with other authors data are given in Table 1.

  

Table 1: Measured Stark FWHM ($W_{\rm m}$) and shift ($d_{\rm m}$) values for the OIII spectral lines at observed electron temperatures (T) and densities (N). a, this work; b, Platisa et al. (1975); c, Puric et al. (1988a); d, Puric et al. (1988b) and e, Blagojevic et al. (2000). $W_{\rm m}/W_{\rm th}$represents the ratio between measured and our calculated (SCPF) values taken from Table 2

Our calculated W and d data at 10²³ m^-3electron density are given in Table 2 for the mean wavelength $<\lambda >$ in the multiplet. The width and shift of each multiplet component can by easily evaluated if one takes into account that the W and d are proportional to $\lambda^2.$

  

Table 2: Electron Stark FWHM (W in pm) and shift (d in pm) calculated by using the semiclassical perturbation formalism (SCPF) (Eqs. (1)-(3)) at 10²³ m^-3 electron density and various electron temperatures (T in 10⁴ K). $<\lambda >$ is the mean wavelength (in nm) in the multiplet. Negative shift is toward the blue
