celestsp 0.2.27

Celestial TSP is a Python script that calculates the optimal order of celestial bodies for observation based on their coordinates.

Celestial TSP

Overview

Celestial TSP calculates optimal observation order for celestial bodies. The script uses the Traveling Salesman Problem (TSP) algorithm to find the shortest path between celestial bodies and generates a spherical image showing the optimal order.

Celestial TSP Planner

positional arguments:
  input_file_path       Input file path with celestial coordinates.

options:
  -h, --help            show this help message and exit
  --lat LAT             Latitude of observation location.
  --lon LON             Longitude of observation location.
  --height HEIGHT       Height of observation location (in meters).
  --date DATE           Observation date (YYYY-MM-DD).
  --time TIME           Observation time (HH:MM:SS).
  --tz TZ               Time zone offset (e.g., +9 for JST).
  --output OUTPUT       Filename for the output image.
  --first_body FIRST_BODY
                        Name of the celestial body to start the TSP from.

Provide the input file containing celestial coordinates and specify the observation location and time.
