This package provides a Python library for reading from and writing to FITS files using the CFITSIO library. Among other things, it can

• read and write image, binary, and ascii table extensions;

• read arbitrary subsets of tables in a lazy manner;

• query the rows and columns of a table;

• read and write header keywords;

• read and write Gzip files.

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

This package implements a functionality of AI-powered automated pipeline for lens modeling, with lenstronomy as the modeling engine.

Features:

• AI-automated forward modeling for large samples of galaxy-scale lenses

• flexible: supports both fully automated and semi-automated (with user tweaks) modes

• multi-band lens modeling made simple

• supports both galaxy–galaxy and galaxy–quasar systems

• effortless syncing between local machines and High-Performance Computing Cluster

SunPy is package for solar physics and is meant to be a free alternative to the SolarSoft data analysis environment.

It includes an interface for searching and downloading data from multiple data providers, data containers for image and time series data, commonly used solar coordinate frames and associated transformations, as well as other functionality needed for solar data analysis.

This package provides a CIANNA - a general-purpose deep learning framework primarily developed and used for astronomical data analysis.

Fitsverify is a computer program that rigorously checks whether a FITS data file conforms to the requirements defined in Version 3.0 of the FITS Standard document.

This package provides a EventSource plugin for ctapipe, needed to read the calibrated data of the MAGIC telescope system.

SkyMaker is a program that simulates astronomical images. It accepts object lists in ASCII generated by the Stuff program to produce realistic astronomical fields. SkyMaker is part of the EFIGI development project.

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

This package provides a CLI and Python module to quickly calculate cosmological parameters e.g. redshift or luminosity-distance.

Colossus is a Python toolkit for calculations pertaining to cosmology, the large-scale structure of the universe, and the properties of dark matter halos.

This package provides an access to the JWST Science Calibration Pipeline processes data from all JWST instruments and observing modes by applying various science corrections sequentially, producing both fully-calibrated individual exposures and high-level data products (mosaics, extracted spectra, etc.).

PetroFit is a package for calculating Petrosian properties, such as radii and concentration indices, as well as fitting galaxy light profiles. In particular, PetroFit includes tools for performing accurate photometry, segmentations, Petrosian profiling, and Sérsic fitting.

Pymcfost is a Python interface to the 3D radiative transfer code MCFOST. The goal is to provide a simple and light interface to explore and plot a single (or a few) model(s).

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

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

This package implements a functionality for calibration of science observations from the Nancy Grace Roman Space Telescope.

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.

This package provides a Square Kilometre Array (SKA) Science Data Processor (SDP) function library for radio astronomy.

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

This package provides a Python definition and validation schemata for FITS files.

Radio Beam is a simple toolkit for reading beam information from FITS headers and manipulating beams. Some example applications include:

• Convolution and deconvolution

• Unit conversion (Jy to/from K)

• Handle sets of beams for spectral cubes with varying resolution between channels

• Find the smallest common beam from a set of beams

• Add the beam shape to a matplotlib plot

SPLASH is visualisation tool for Smoothed Particle Hydrodynamics (SPH) simulations in one, two and three dimensions, developed mainly for astrophysics. It uses a command-line menu but data can be manipulated interactively in the plotting window.

Orbital is a high level orbital mechanics package for Python.
