LMC + Galaxy coordinate system

We adopt the following coordinate system and position-velocity values:

• X-axis along the Sun-Galactic Center line.
• Y-axis along the direction of LSR motion.
• Z-axis in the direction of the NGP.
• IAU value of R₀=8.5 kpc.
• Distance to LMC=50.1 kpc (Freeman et al. 2001).
• Angular position of LMC l = 280.47, b = -32.89 (1976 RC2)
• Space velocity from Kallivayalil et al. (2005): U = -86.0, V = -268.0, W= 252.0

E.g. the LSR position is (-8.5, 0, 0) in kpc. The following diagram and VRML if you click describes the geometry:

The "ghostly" plane is the orbital plane along with the angular momentum vector. The positional vectors are to scale, the velocity and angular momentum vectors only show direction.
