 Dear gmx users, 

I want to compute the angle between two groups. I used g_sgangle -s
topol.tpr -f conf.gro -n index.ndx -oa sg_angle.xvg. 
As I understand the first column refer to time and the second refer to
angle. What does the thrid column refer to in xvg file? 

@    xaxis  label "Time (ps)" 
@    yaxis  label "Angle (degrees)" 
@TYPE xy 
           0             1     0.0197823 
        0.05            1             0 
         0.1             1             0 
        0.15            1     0.0197823 
         0.2             1             0 

Can you give an answer, please?
