What do you mean with that? I mean in respect to what I was pointing out?
Apollo attitudes (at least for the PADs) were given in the order roll, pitch, yaw, instead of the order pitch, roll, yaw that you nominated. So the Apollo 15 TLI burn attitude is roll=180°, pitch=45°, yaw=1°.
Apollo's coordinate systems are not easy to be understood. The coordinates are given relative to the current IMU stable member orientation. And this orientation depends on the mission phase and available reference stars.
This true and means that a fully prograde burn could have a yaw angle of say 45° (or any other number you care to pick), depending on the orientation of the REFSMMAT. That said, the REFSMMAT used for TLI was the same as that set on the launch pad so a yaw of 1° indicates that there was an off-plane component to the burn. This is expected given that you can't launch directly from KSC (lat ~28.608) into the moon's orbital plane (inc ~18.294 to ~28.584). This off-plane component was used to setup an off-plane transfer, ie, the orbital plane of the CSM post-TLI was neither that of the launch nor that of the moon, but somewhere in between.
Regarding plane changes in lunar orbit, there were two times when these would typically occur:
1. During the LM landed phase the CSM would do a plane change to account for the precession of its orbit (due to the rotation of the moon) relative to the LM position. Apollo 11 didn't do this maneuvoure due to the short amount of time the LM was on the surface.
2. During rendezvous, a plane change by the LM could be done, either as a separate maneuvoure or as part of a larger phasing burn.
