PointXP Analysis explained


Hello experts,
pointxp works great, gives a lot of details, but I have no idea what all the analysis tells me.
E.g. what does "Sensitivity mean" (I have 280)
Pointing error RMS 12,8" (for a completely selfemade mount quite good?)
Axis Alignment Error: does this refer to polaralignment?
What tells me the Grafical Error Analysis? Theta, Phi
I know its quite a theoretical question, but I'd like to understand the things behind (almost a litle bit...)
