Identifying Stellar Motions associating different Spiral Arm Scenarios
Results
Data
-N-body spiral arms + SPH / corotating (Kawata14) 90deg.dat
-N-body spiral arms / rigid-body rotation (Manifolds?) (RodcaFabrega13)
-Test particle TWA spiral arms / density wave (RocaFabrega14)
-Test particle Ferrers bar + response spiral arms / rigid-body rotation (Manifolds?) (RomeroGomez14)
In each row:
G ,Grvs ,Xreal (Kpc),Yreal (Kpc),Zreal (Kpc),VXreal (Km/s),VYreal (Km/s),VZreal (Km/s),Xobs (Kpc),Yobs (Kpc),Zobs (Kpc), VXobs (Km/s),VYobs (Km/s),VZobs (Km/s)
Positions and velocities are galactocentric. The Sun is placed at (-8.5,0,0)Kpc
data format: (2(f7.3,1x),3(f7.3,1x),3(f10.2,1x),3(f7.3,1x),3(f10.2,1x))
Real values = without errors -Obs values = with Gaia errors
