Code to plot the Proper Motion anomaly (PMa) of any star in the Kervella+2022 Vizier catalog. The code follows the method detailed in Kervella+2019.
An example of how to use the code is given in example/PMa_example.py with the potential kwargs that can be given to the different functions.
- self.data: DataFrame with queried PMa information from Gaia eDR3 and Hipparcos + any geometry information given for the system
- plot_pma(ax, epoch=['eDR3' or 'Hipparcos']): Returns ax where the specifc PMa curve is plotted
- plot_disc_extent(ax, discdata): Returns ax where the disc extent is plotted as well as a Hill radius argument for the stability of the inner edge location.
