This package provides an interface to Heliophysics Application Programmer’s Interface data server API.

The package is based around `torus mapping', which is a non-perturbative technique for creating orbital tori for specified values of the action integrals. Given an orbital torus and a star's position at a reference time, one can compute its position at any other time, no matter how remote.

SpacePy is a package for Python, targeted at the space sciences, that aims to make basic data analysis, modeling and visualization easier. It builds on the capabilities of NumPy and MatPlotLib packages.

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

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

Python implementation of Parker wind models for planetary atmospheres. p-winds produces simplified, 1-D models of the upper atmosphere of a planet, and perform radiative transfer to calculate observable spectral signatures.

The scalable implementation of 1D models allows for atmospheric retrievals to calculate atmospheric escape rates and temperatures. In addition, the modular implementation allows for a smooth plugging-in of more complex descriptions to forward model their corresponding spectral signatures (e.g., self-consistent or 3D models).

The Advanced Scientific Data Format (ASDF) is a next-generation interchange format for scientific data. This package contains the Python implementation of the ASDF Standard.

Westerbork Synthesis Radio Telescope (WSRT) measures data.

This package implements a functionality to handle solar and geomagnetic indices needed for scientific and operational projects.

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

madrigalWeb is a pure python module to access data from any Madrigal database.

Madrigal is an upper atmospheric science database used by groups throughout the world. Madrigal is a robust, World Wide Web based system capable of managing and serving archival and real-time data, in a variety of formats, from a wide range of upper atmospheric science instruments. Data at each Madrigal site is locally controlled and can be updated at any time, but shared metadata between Madrigal sites allow searching of all Madrigal sites at once from any Madrigal site.

CDF or CDF Library is a scientific data management package which allows programmers and application developers to manage and manipulate scalar, vector, and multi-dimensional data arrays.

The CDF is a self-describing data abstraction for the storage and manipulation of multidimensional data in a platform- and discipline-independent fashion.

This package provides library and binary utilities to manipulate CDF files.

This package provides base classes and command-line tools for implementing calibration pipeline software.

Funtools is a minimal buy-in FITS library and utility package originally developed at the the High Energy Astrophysics Division of SAO. Although no longer actively supported at SAO, it is still widely used within the astronomical community, especially among X-ray astronomers.

The Funtools library provides simplified access to a wide array of file types: standard astronomical FITS images and binary tables, raw arrays and binary event lists, and even tables of ASCII column data. A sophisticated region filtering library (compatible with ds9) filters images and tables using Boolean operations between geometric shapes, support world coordinates, etc. Funtools also supports advanced capabilities such as optimized data searching using index files.

SPICE is an ancillary information system developed by NASA for planetary science missions. It enables the computation of geometric and event data required for analyzing and planning scientific observations obtained from spacecraft. In addition, it plays a crucial role in mission planning and executing various engineering functions necessary for successful mission completion.

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

LePHARE is a code for estimating galaxy redshifts and physical parameters using template fitting.

This package implements a functionality to import data from the Madrigal database (upper atmospheric science database) into pysat.

This package includes plugins that provide ASDF serialization support for Astropy objects.

LibXISF is C++ library that can read and write XISF files produced by PixInsight. It implements XISF 1.0 specification.

flatstar is a pure-Python tool for drawing stellar disks with scientifically-rigorous limb darkening. Each pixel has an accurate fractional intensity in relation to the total stellar intensity of 1.0. It is ideal for ray-tracing simulations of stars and planetary transits.

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.

Stellarium is a planetarium. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars, or a telescope. It can be used to control telescopes over a serial port for tracking celestial objects.
