As shown in Tables 4 and 5,line flux derived in the present work is systematically lower than that in W06.This ismainly due to two reasons.(1)W06 considered the corrections of interstellar gas absorption in the flux calculation by assuming a hydrogen column density of 6×1021cm-2which corresponds to the density of 1 H cm-3and the distance of1.9 kpc.The flux values listed in W06 were compensated by absorption values,which shower higher values.(2)The contributions of satellite lines are subtracted during our flux calculation.Although there is a systematic difference in absolute line flux between the calculations of W06 and ours,after calculating the G-ratio[2]which is used to estimate the plasma temperature with
