store initialization ro,vo,zo, and solarmotion and use it when calling RA, Dec, etc. without explicit coordinate conversion parameters (fixes #158)
additional tests for new coordinate-conversion parameters storing (issue #158)
change default vo and ro to 220 and 8
add position decorator to return quantities as physical if a scale was given upon initialization, apply this to R, z, x, and y; changes to default ro and vo to know whether these were given or not
support for plotting in physical coordinates
decorate rap and rperi for Full and RZOrbits with physical_position
tweaks for plotting when specificying that you want physical coordinates
start on tests for physical outputs
decorate rap and rperi for Full and RZOrbits with physical_position
decorate velocities with physical_velocity
plotting of the velocities in km/s
3D plotting with physical parameters
support for plotting the time in physical units
add documentation on new physical coordinates plotting; add this also to the HISTORY
fix introduced plotting bug in plot2d
tweaks to streamdf to deal with new orbit attributes
fix logic in deciding whether to plot in physical coordinates
