How is the cavity gfactor accounted for in this calculation?

I assume that pointing noise and dc misalignment couples 00 to 01 by a factor theta / theta_cavity
Inside the cavity 01 is suppressed by 2/pi*F*sin(arccos(sqrt(g_cav))).
For the XARM this number is 116 taking gfactor to be 0.32. So all pointing noise couples to power RIN.
Suppression factor inside PRC is 6.5 for gfactor 0.97. This means that 85% of jitter couples to RIN, I accounted for this factor while converting RIN to angle.
I did not consider translational motion of the beam. But still PRC RIN can not be explained by oples readings as we can see exciting optics in pitch and yaw. I suspect this RIN is due to PR3, as it can create stronger motion in yaw than in pitch due to incident angle and translational motion of the mirror. I do not have a number yet.
