This package provides tools for COS.

This package implements functionality for decomposition of Hydrogen content of simulation particles into neutral/ionized and atomic/molecular. Implementations of Blitz & Rosolowsky (2006) and Rahmati et al (2013).

Python package for making visuals of gravitational wave signals, specifically pulsar timing array signals.

Generalized World Coordinate System (GWCS) is an Astropy affiliated package providing tools for managing the World Coordinate System of astronomical data.

GWCS takes a general approach to the problem of expressing transformations between pixel and world coordinates. It supports a data model which includes the entire transformation pipeline from input coordinates (detector by default) to world coordinates.

ZodiPy is an package for simulating zodiacal light in intensity for arbitrary solar system observers.

This package implements functionality of Point Spread Function describing how the optical system spreads light from sources.

Halotools is a specialized python package for building and testing models of the galaxy-halo connection, and analyzing catalogs of dark matter halos. The core feature of Halotools is a modular platform for creating mock universes of galaxies starting from a catalog of dark matter halos obtained from a cosmological simulation.

This package provides an extending scripting capabilities, present natively in Siril.

This package provides a tooling for solar X-ray spectroscopy based on SunPy.

This package provides a sunpy FIDO plugin for accessing data in the Solar Orbiter Archive.

SPISEA is an python package that generates single-age, single-metallicity populations (i.e. star clusters). It gives the user control over many parameters:

• cluster characteristics (age, metallicity, mass, distance)

• total extinction, differential extinction, and extinction law

• stellar evolution and atmosphere models

• stellar multiplicity and Initial Mass Function

• initial-Final Mass Relation

• photometric filters

This package provides a Python wrapper for tempo2 - a high precision pulsar timing tool.

This package provides a history of astronomy library. Current Features:

• define standard positional numeral systems with standard arithmetics (BasedReal)

• set your own precision contexts and algorithms on arithmetical operations (PrecisionContext)

• keep track of all operations

• build or import ancient astronomical tables

• perform arithmetical and statistical operations

• support for BasedReal values

• define new calendar types

• date conversions

• collection of mathematical models used for all kinds of geocentric astronomical tables

This package provides a cython-optimized implementations of empirical dust exitinction laws found in the literature.

Glue is a python project to link visualizations of scientific datasets across many files.

hvpy is a Python API wrapper around the formal https://api.helioviewer.org/docs/v2/.

BayesicFitting is a package for model fitting and Bayesian evidence calculation, it is a Python version of the the fitter classes in HCSS. HCSS was the all encompassing software system for the operations and analysis of the ESA satellite Herschel.

romanisim is a Galsim-based simulator of imaging data from the WFI on the Nancy Grace Roman Space Telescope (pronounced roman-eye-sim, stylized Roman I-Sim). It uses Galsim to render astronomical scenes, WebbPSF to model the point spread function, and CRDS to access the calibration information needed to produce realistic WFI images.

The casa-formats-io package is a small package which implements functionality to read data stored in CASA formats (such as .image datasets). This implementation is independent of and does not use casacore.

SWIFTGalaxy is an astrophysics module that extends SWIFTSimIO tailored to analyses of particles belonging to individual galaxies simulated with SWIFT. It inherits from and extends the functionality of the SWIFTDataset. It understands the content of halo catalogues (supported: Velociraptor, Caesar, SOAP) and therefore which particles belong to a galaxy or other group of particles, and its integrated properties. The particles occupy a coordinate frame that is enforced to be consistent, such that particles loaded on-the-fly will match e.g. rotations and translations of particles already in memory. Intuitive masking of particle datasets is also enabled. Utilities to make working in cylindrical and spherical coordinate systems more convenient are also provided. Finally, tools to iterate efficiently over multiple galaxies are also provided.

CZML3 is a Python library to write CZML, a JSON format for describing a time-dynamic graphical scene, primarily for display in a web browser running Cesium.

This package provides a Python module to various STScI image array manipulation functions.

SPOT (Site Planning and Observation Tool) is a graphical tool for planning and conducting astronomical observations at a site.

uranimator is a CLI tool that works with your existing (code uraniborg) install to create animations. See how the sky evolves over a million years or what traveling to a star 100 light years away looks like.
