# pystrometry - Support for high-precision astrometry timeseries analysis

### Example usage - Plotting the orbital motion with default parameters

from pystrometry.pystrometry import OrbitSystem from collections import OrderedDict

orb = OrbitSystem() # default parameters orb.plot_orbits()

  • Define the orbital parameters

    attribute_dict = OrderedDict([ (‘RA_deg’, 164.),

    (‘DE_deg’, -21.), (‘absolute_plx_mas’, 27.), (‘Tp_day’, 57678.4), (‘omega_deg’, -23.), (‘P_day’, 687.), (‘ecc’, 0.08), (‘OMEGA_deg’, 114.), (‘i_deg’, 31.), (‘m1_MS’, 0.9), (‘m2_MJ’, 3.)])

    orb = OrbitSystem(attribute_dict) orb.plot_orbits()

Get the proper motion in RA, Dec:

t_mjd = np.linspace(50000, 52000) delta_ra_star_mas, delta_dec_mas = orb.ppm(t_mjd)
