Coordinates in JAX

Project description

coordinax

Coordinates in JAX

Coordinax enables calculations with coordinates in JAX. Built on Equinox and Quax.

Installation

PyPI platforms PyPI version

pip install coordinax

Documentation

Documentation Status

Coming soon. In the meantime, if you've used astropy.coordinates, then coordinax should be fairly intuitive.

Quick example

import coordinax as cx
import jax.numpy as jnp
from unxt import Quantity

q = cx.CartesianPos3D(
    x=Quantity(jnp.arange(0, 10.0), "km"),
    y=Quantity(jnp.arange(5, 15.0), "km"),
    z=Quantity(jnp.arange(10, 20.0), "km"),
)
print(q)
# <CartesianPos3D (x[km], y[km], z[km])
#     [[ 0.  5. 10.]
#      [ 1.  6. 11.]
#      ...
#      [ 8. 13. 18.]
#      [ 9. 14. 19.]]>

q2 = cx.represent_as(q, cx.SphericalPos)
print(q2)
# <SphericalPos (r[km], theta[rad], phi[rad])
#     [[11.18   0.464  1.571]
#      [12.57   0.505  1.406]
#      ...
#      [23.601  0.703  1.019]
#      [25.259  0.719  0.999]]>

p = cx.CartesianVel3D(
    d_x=Quantity(jnp.arange(0, 10.0), "m/s"),
    d_y=Quantity(jnp.arange(5, 15.0), "m/s"),
    d_z=Quantity(jnp.arange(10, 20.0), "m/s"),
)
print(p)
# <CartesianVel3D (d_x[m / s], d_y[m / s], d_z[m / s])
#     [[ 0.  5. 10.]
#      [ 1.  6. 11.]
#      ...
#      [ 8. 13. 18.]
#      [ 9. 14. 19.]]>

p2 = cx.represent_as(p, cx.SphericalVel, q)
print(p2)
# <SphericalVel (d_r[m / s], d_theta[m rad / (km s)], d_phi[m rad / (km s)])
#     [[ 1.118e+01 -3.886e-16  0.000e+00]
#      [ 1.257e+01 -1.110e-16  0.000e+00]
#      ...
#      [ 2.360e+01  0.000e+00  0.000e+00]
#      [ 2.526e+01 -2.776e-16  0.000e+00]]>
