We newly identify 402 spectra of 346 strong [O III]{\\lambda}5007 emission-line compact galaxies by finding compact isolated point sources. Combined with the samples in our previous work (Liu et al. 2022), this returns a sample of 1830 unique strong [O III]{\\lambda}5007 emission-line compact galaxies with 2033 spectra of z <= 0.53.
