摘要We used multi-component profiles to model the H beta and [O III]lambda lambda 4959,5007 lines of SDSS J143030.22-001115.1, a narrow-line Seyfert 1 galaxy (NLS1) in a sample of 150 NLS1 candidates selected from the Sloan Digital Sky Survey (SDSS), Early Data Release (EDR). After subtracting the H beta contribution from narrow line regions (NLRs), we found that its full width half maximum (FWHM) of broad H beta line is nearly 2900 km s(-1), significantly larger than the customarily adopted criterion of 2000 km s(-1). With its weak Fe II multiples, we believe that SDSS J143030.22-001115.1 should not be classified as a genuine NLS1. When we calculate the virial black hole masses of NLS1s, we should use,the H beta linewidth after subtracting the NLR component.
