Astronomical utilities for PANOPTES

PANOPTES Utilities

Utility functions for use within the Project PANOPTES ecosystem and for general astronomical processing.

This library defines a number of modules that contain useful functions as well as a few services.

Install

To install type:

pip install panoptes-utils

Full options for install:

pip install "panoptes-utils[config,docs,images,testing,social]"

See the full documentation at: https://panoptes-utils.readthedocs.io

Dependencies

There are a few system dependencies depending on what functionality you will be using.

In particular, the plate solving requires astrometry.net and the appropriate index files.

Use the following on a debian-based system (e.g. Ubuntu) to easily install all dependencies:

apt-get update && apt-get install --no-install-recommends --yes \
  libffi-dev libssl-dev \
  astrometry.net astrometry-data-tycho2 \
  dcraw exiftool libcfitsio-dev libcfitsio-bin \
  libfreetype6-dev libpng-dev libjpeg-dev libffi-dev

Command Line

The panoptes-utils command line tool is available for use with subcommands corresponding to the modules in this library. Currently, the only implemented subcommand is image, which includes commands for converting cr2 files into jpg and/or fits files as well as for plate-solving fits images.

The panoptes-utils image watch <path> command will watch the given path for new files and convert them to jpg and/or fits files as they are added.

See panoptes-utils --help and panoptes-utils image --help for details.

Config Server

There is a simple key-value configuration server available as part of the module.

After installing with the config option as above, type:

panoptes-config-server run --config-file <path-to-file.yaml>

Development with Hatch

This project uses the Hatch build system and environment management.

Prerequisites:

• Python 3.12+
• Hatch: https://hatch.pypa.io (install via pipx install hatch or pip install --user hatch).

Basic workflow:

• Create and enter a dev environment with all testing tools:

  hatch env create
  hatch shell
  # or run commands without activating the shell using `hatch run ...`
  

• Install optional extras as needed (choose any):

  # Examples: google, focuser, sensors, weather
  hatch run pip install -e ".[config,images,testing]"
  

• Run tests:

  # All tests with coverage, using pytest options from pyproject.toml
  hatch run pytest
  
  # Single test file
  hatch run pytest tests/test_utils.py
  

• Lint / style checks:

  # Lint (Ruff)
  hatch run lint
  # Format (Ruff)
  hatch run fmt
  # Check formatting without changes
  hatch run fmt-check
  

• Build the package (wheel and sdist):

  hatch build
  

• Run the CLI locally (Typer app):

  hatch run pocs --help
  

• Versioning: Version is derived from git tags via hatch-vcs. To produce a new version, create and push a tag (e.g., v0.1.0).

[Testing]

To test the software, prefer running via Hatch so the right environment and options are used:

hatch run pytest

By default all tests will be run. If you want to run one specific test, give the specific filename as an argument to pytest:

hatch run pytest tests/test_mount.py
