请问采用S分析组的分析中改成一个圆偏振光源时,分析的script一直报错, Error: prompt line 81: in getdata, the d-card named source was not found. Try the command '?getdata;' to see which d-cards are available. Error: Result T: variable not found. Error: Result R: variable not found. Error: Result S: variable not found. Error: Result S_polarization: variable not found. 怎么修改
