such as on Mars or an exoplanet orbiting a star with a non-solar spectrum of
radiation.

This package consists of three parts:

@itemize

model to enable rendering.

@item @code{libShowMySky} library that lets the applications render the
atmosphere model.

rendering of the atmosphere model and examine its properties.

Gpredict can also predict the time of future passes for a satellite, and
provide you with detailed information about each pass.

Some core features of Gpredict include:

@itemize
@item Tracking of a large number of satellites only limited by the physical
memory and processing power of the computer
@item Display the tracking data in lists, maps, polar plots and any
combination of these
@item Have many modules open at the same either in a notebook or in their own
windows.  The modules can also run in full-screen mode
@item You can use many ground stations
@item Predict upcoming passes
@item Gpredict can run in real-time, simulated real-time (fast forward and
backward), and manual time control
@item Detailed information both the real time and non-real time modes
@item Doppler tuning of radios via Hamlib rigctld

     "This package provides a librari for spherical harmonic
transforms (SHTs), which evolved from the libpsht library, addressing several
of its shortcomings, such as adding MPI support for distributed memory systems
and SHTs of fields with arbitrary spin, but also supporting new developments
in CPU instruction sets like the Advanced Vector Extensions (AVX) or fused
multiply-accumulate (FMA) instructions.  The library is implemented in
portable C99 and provides an interface that can be easily accessed from other
programming languages such as C++, Fortran, Python etc.  Generally, libsharp's
performance is at least on par with that of its predecessor; however,
significant improvements were made to the algorithms for scalar SHTs, which
are roughly twice as fast when using the same CPU capabilities.

formats, including EPS, PDF, PS, PNG, and SVG.

Main features:
@itemize
@item Make plots interactively or using scripts
@item Show grayscale, colorscale, and 3-color RGB images of FITS files
@item Generate co-aligned FITS cubes to make 3-color RGB images
@item Make plots from FITS files with arbitrary WCS (e.g. position-velocity)
@item Slice multi-dimensional FITS cubes
@item Overlay any number of contour sets
@item Overlay markers with fully customizable symbols
@item Plot customizable shapes like circles, ellipses, and rectangles
@item Overlay ds9 region files
@item Overlay coordinate grids
@item Show colorbars, scalebars, and beams
@item Customize the appearance of labels and ticks
@item Hide, show, and remove different contour and marker layers
@item Pan, zoom, and save any view as a full publication-quality plot

    (description "Ginga is a toolkit designed for building viewers for
scientific image data in Python, visualizing 2D pixel data in numpy arrays.  It
can view astronomical data such as contained in files based on the
FITS (Flexible Image Transport System) file format.  It is written and is
maintained by software engineers at the National Astronomical Observatory of
Japan (NAOJ), the Space Telescope Science Institute (STScI), and other
contributing entities.

The Ginga toolkit centers around an image display object which supports zooming
and panning, color and intensity mapping, a choice of several automatic cut
levels algorithms and canvases for plotting scalable geometric forms.  In
addition to this widget, a general purpose \"reference\" FITS viewer is
provided, based on a plugin framework.  A fairly complete set of standard plugins
are provided for features that we expect from a modern FITS viewer: panning and
zooming windows, star catalog access, cuts, star pick/FWHM, thumbnails, etc.")

     "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 @url{http://hst-crds.stsci.edu} or
@url{https://jwst-crds.stsci.edu/} which record information about reference
files and provide related services.")

It combines data, uncertainties, units, metadata, masking, and coordinate
transformations into classes with unified slicing and generic coordinate
transformations and plotting/animation capabilities.  It is designed to handle
data of any number of dimensions and axis types (e.g. spatial, temporal,
spectral, etc.) whose relationship between the array elements and the real world
can be described by @acronym{WCS, World Coordinate System} translations.")

simulates physical optical propagation including diffraction.  It implements a
flexible framework for modeling Fraunhofer and Fresnel diffraction and point
spread function formation, particularly in the context of astronomical
telescopes.

POPPY was developed as part of a simulation package for the James Webb Space
Telescope, but is more broadly applicable to many kinds of imaging simulations.
It is not, however, a substitute for high fidelity optical design software such
as Zemax or Code V, but rather is intended as a lightweight alternative for
cases for which diffractive rather than geometric optics is the topic of
interest, and which require portability between platforms or ease of scripting.")

    (description
     "This package provides a Python implementation for computations of the
position and velocity of an earth-orbiting satellite, given the satellite’s
@acronym{TLE, Two-line element set} orbital elements from a source like
@url{CelesTrak, https://celestrak.org/}.

It implements the most recent version of @acronym{SGP4, Simplified General
Perturbation models}, and is regularly run against the SGP4 test suite to make
sure that its satellite position predictions agree to within 0.1 mm with the
predictions of the standard distribution of the algorithm.  This error is far
less than the 1–3 km/day by which satellites themselves deviate from the ideal
orbits described in TLE files.")

@item automatic grouping of catalogues on the sky

shift using fast pattern-matching
