Evaluation of the SNR. (a) Data on the spectrum of the 3d orbital of Sr. The number of accumulations is 230. (b) SNR of 3d orbitals of Sr. The horizontal axis is the number of accumulations and the vertical axis is the SNR. (c) Data on the spectrum of the 4d orbital of Sr. The number of accumulations is 230. (d) SNR of 4d orbitals of Sr. The horizontal axis is the number of accumulations and the vertical axis is the SNR. |
