This package provides an yt extension package for astrophysical analysis. This package contains functionality for:

• halo finding and analysis

• lightcones

• planning cosmological simulations for making lightcones and lightrays

• exporting to the RADMC-3D radiation transport code

• creating PPV FITS cubes

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

This package contains FIT and CSV files required for WebbPSF installation and distributed separately from it.

CRDS is a package used for working with astronomical reference files for the HST and JWST telescopes. CRDS is useful for performing various operations on reference files or reference file assignment rules. CRDS is used to assign, check, and compare reference files and rules, and also to predict those datasets which should potentially be reprocessed due to changes in reference files or assignment rules. CRDS has versioned rules which define the assignment of references for each type and instrument configuration. CRDS has web sites corresponding to each project http://hst-crds.stsci.edu or https://jwst-crds.stsci.edu/ which record information about reference files and provide related services.

sunraster is an Python library that provides the tools to read in and analyze spectrogram data.

The DKIST package aims to help you search, obtain and use DKIST data as part of your Python software.

This package provides pysatSpaceWeather - a Python module, which contains routines to load common historic, real-time, and forecasted space weather indices as pysat.Instrument objects.

ctaplot provides low-level reconstruction quality-checks metrics computation and vizualisation for Imaging Atmospheric Cherenkov Telescopes such as CTA.

STScI tools and algorithms used in calibration pipelines.

This package provides schema definitions for the Data Formats For Gamma-Ray Astronomy.

radiospectra provides support for some type of radio spectra in solar physics.

Python Tools for HST ACS (Advanced Camera for Surveys) Data.

PyHDRL provides a Python 3 API (language bindings) for the ESO High Level Data Reduction Library (HDRL) using pybind11. It allows for using the ESO High Level Data Reduction Library in Python scripts, or directly in an interactive Python session, and thus allows for using HDRL algorithms in recipes implemented in Python as part of an instrument pipeline package.

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).

PyEsoRex is a command line tool which can serve as a drop-in replacement of EsoRex, which can execute both, existing pipeline recipes implemented using the Common Pipeline Library C API, and recipes implemented using the PyCPL Python API.

FITS/XISF image viewer with multithreaded image loading. It is intended primarily for viewing astro photos and images with support of following formats:

• FITS 8, 16 bit integer and 32 bit float

• XISF 8, 16 bit integer and 32 bit float

• RAW CR2, DNG, NEF

• JPEG, PNG, BMP, GIF, PBM, PGM, PPM and SVG images

Features:

• using same stretch function as PixInsight

• OpenGL accelerated drawing

• index and search FITS XISF header data

• quick mark images and then copy/move marked files

• convert FITS <-> XISF

• convert FITS/XISF -> JPEG/PNG

• image statistics mean, media, min, max

• support for WCS

• thumbnails

• convert CFA images to colour - debayer

• color space aware

This package contains a pure-python drop-in replacement for the Python wrapper around the original LOFAR ParameterSet that is written in C++. It supports only the basic features of the original.

Cobaya, and Spanish for Guinea Pig) is a framework for sampling and statistical modelling: it allows you to explore an arbitrary prior or posterior using a range of Monte Carlo samplers (including the advanced MCMC sampler from CosmoMC, and the advanced nested sampler PolyChord). The results of the sampling can be analysed with GetDist. It supports MPI parallelization (and very soon HPC containerization with Docker/Shifter and Singularity).

This package implements a functionality to parse DS9 region files.

This package provides utilities for accessing EAGLE public database.

skyfield computes positions for the stars, planets, and satellites in orbit around the Earth. Its results should agree with the positions generated by the United States Naval Observatory and their Astronomical Almanac to within 0.0005 arcseconds (half a mas or milliarcsecond).

This package provides a functionality to reproject astronomical images using various techniques via a uniform interface, where reprojection is the re-gridding of images from one world coordinate system to another e.g. changing the pixel resolution, orientation, coordinate system.

The concept of the pvextractor package is simple - given a path defined in sky coordinates, and a spectral cube, extract a slice of the cube along that path, and along the spectral axis, producing a position-velocity or position-frequency slice.

This package provides astronomical interstellar dust extinction curves implemented using the astropy.modeling framework.
