Pip-installable Astronomy Data Files

A collection of Python packages that provide commonly used astronomy data files in pip-installable format. Each package contains specific datasets commonly required for astrodynamics and astronomical calculations.

Available Packages

NAIF Kernels

• naif_de440: NAIF Development Ephemeris (DE) 440 for SPICE
• naif_leapseconds: NAIF Leapseconds Kernel for SPICE
• naif_earth_itrf93: NAIF Earth Body-fixed Reference Frame/Body Association Kernel
• naif_eop_historical: NAIF Historical Earth Orientation Parameters Kernel
• naif_eop_predict: NAIF Longterm Prediction Earth Orientation Parameters Kernel
• naif_eop_high_prec: NAIF High Precision Earth Orientation Parameters Kernel

Ephemerides

• jpl_small_bodies_de441_n16: JPL Small Bodies Ephemeris (DE) 441 of 16 most massive asteroids

Observatory Data

• mpc_obscodes: Minor Planet Center Observatory Codes database

Installation

Each package can be installed independently via pip:

pip install naif-de440
pip install naif-leapseconds
pip install mpc-obscodes
# ... etc

Usage Example

import spiceypy as sp
from naif_de440 import de440
from naif_leapseconds import leapseconds
from mpc_obscodes import obscodes

# Load SPICE kernels
sp.furnsh(de440)
sp.furnsh(leapseconds)

# Access observatory codes
observatory_data = obscodes.load()

These packages automatically handle data file distribution and provide consistent interfaces for accessing astronomy datasets.
