Version 1.6.1 documentation

across-tools

The across-tools repository is the NASA-ACROSS library to perform specific astronomy-related calculations on the data hosted in the across-server. This repository is responsible for instrument bandpasses, footprint, ephemeris, two-line element (tle) analysis, and observatory/instrument visibility calculations.

Installation

This repository can be installed on python (version >=3.10) environments.

#activate your python environment (conda, mamba, venv... etc)
git clone https://github.com/NASA-ACROSS/across-tools.git
cd across-tools
python -m pip install .

or the latest released version with pip

python -m pip install across-tools

Usage

Below is a small example on how to utilize the tools to initialize a simple footprint, and perform a healpix query on a projected instrument footprint.

from across.tools import Coordinate
from across.tools import Polygon
from across.tools.footprint import Footprint

simple_polygon = Polygon(
   coordinates=[
      Coordinate(ra=-0.5, dec=0.5),
      Coordinate(ra=0.5, dec=0.5),
      Coordinate(ra=0.5, dec=-0.5),
      Coordinate(ra=-0.5, dec=-0.5),
      Coordinate(ra=-0.5, dec=0.5)
   ]
)
footprint = Footprint(detectors=[simple_polygon])

projected_footprint = footprint.project(
   coordinate=Coordinate(ra=42, dec=42), roll_angle=45
)
pixels = projected_footprint.query_pixels()
