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

Python read-only implementation of the EventIO file format.

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

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.

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.

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

This package implements a reader for CORSIKA binary output files using NumPy.

This package includes an extension for the Python library asdf to add support for reading and writing chunked Zarr arrays, a file storage format for chunked, compressed, N-dimensional arrays based on an open-source specification.

Westerbork Synthesis Radio Telescope (WSRT) measures data.

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 includes plugins that provide ASDF serialization support for Astropy objects.

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.

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

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

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.

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.

STPSF produces simulated PSFs for the James Webb Space Telescope, NASA's flagship infrared space telescope. STPSF can simulate images for any of the four science instruments plus the fine guidance sensor, including both direct imaging, coronagraphic, and spectroscopic modes.

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.

This package consists of Python replacements for functions that are part of the IDL built-in library or part of astronomical IDL libraries. The emphasis is on reproducing results of the astronomical library functions. Only the bare minimum of IDL built-in functions are implemented to support this.

Package Raccoon cleans the "wiggles" (i.e., low-frequency sinusoidal artifacts) in the JWST-NIRSpec IFS (integral field spectroscopy) data. These wiggles are caused by resampling noise or aliasing artifacts.

FITS/XISF image viewer with multithreaded image loading. It is intended primarily for viewing astro photos and images. It supports the 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

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.

This package provides a plugin to fake subprocess for pytest. The plugin adds the fake_process fixture (and fp as an alias). It can be used it to register subprocess results so you won't need to rely on the real processes. The plugin hooks on the subprocess.Popen(), which is the base for other subprocess functions. That makes the subprocess.run(),subprocess.call(), subprocess.check_call() and subprocess.check_output() methods also functional.
