| 摘要 | We have studied the spectral properties in the soft X-ray (0.1-2.0 keV), hard X-ray (2.0-10.0 keV), and gamma-ray energy bands for a sample of bright gamma-ray (E > 100MeV) blazars. In our analysis, we used the methods of weighted and un-weighted correlation analysis using a non-parametric Spearman rank test. Our results indicate: (i) there are significant anti-correlations both between the soft X-rays and gamma-rays spectral shapes and between hard X-ray and gamma-ray of flat spectrum radio quasars (FSRQs) and BL Lac objects; (ii) the weighted correlation analysis on spectral indices gives a positive correlation while the un-weighted analysis gives a negative correlation between the soft and hard X-ray bands, yielding contrary results. Because the weighted correlation analysis eliminates the effect of the observational errors, we may believe that the results of weighted analysis are more reliable than those of the un-weighted analysis. |
