Incidence angle and profile angle of unlimited trackers

[Doris]

One of my variants has the unlimited sheds chosen. I copied it and changed the orientation to unlimited trackers. The phi min and phi max were set to -22°, which I believed to be the same as the 22° in the umlimited sheds. While all other inputs remain the same (I meant I changed nothing else...), why are the incidence angle and profile angle of the unlimited trackers different from that of the unlimited sheds?

Unlimited sheds are facing south, unlimited tracker at -22 are facing east.
