用DCF方法分析S5 0716+714的光变特性

The Method of DCF for Analyzing Optical Variability of S5 0716+714

利用DCF方法对S5 0716+714从1994年到2003年的15 073个光学波段数据和1990年到2004年的射电波段22GHz、37GHz的310个数据,分析了S5 0716+714射电波段间、光学波段间、射电与光学波段间的光学相关性与时延.得出了S5 0716+714射电波段间、光学波段间、射电与光学波段间存在较强的相关性和高频段的变化超前于低频段的变化的结论,支持了Blazar的标准模型.

The method of discrete correlation function is used to the 15 073 optical dates from 1994 to 2003 and the 310 radio dates from 1990 to 2004 of S5 0716＋714,to get the correlation analysis results of optical and radio.The results shown between different bands there are strong correlation,and the higher frequency variation leads the lower＇s.these supported the blazars＇ standard model.
