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.

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

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

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.")

these sources from a wide variety of models, whether from grid-based
simulation codes such as FLASH, Enzo, and Athena, to particle-based codes such
as Gadget and AREPO, and even from datasets that have been created 'by hand',
such as from NumPy arrays.  pyXSIM also provides facilities for manipulating
the synthetic observations it produces in various ways, as well as ways to
export the simulated X-ray events to other software packages to simulate the
end products of specific X-ray observatories.")

into a single image.  This library is derived from code used in DrizzlePac.
Like DrizzlePac, most of the code is implemented in the C language.  The
biggest change from DrizzlePac is that this code passes an array that maps the
input to output image into the C code, while the DrizzlePac code computes the
mapping by using a Python callback.  Switching to using an array allowed the
code to be greatly simplified.")

Some features include orbit propagation, solution of the Lambert's problem,
conversion between position and velocity vectors and classical orbital
elements and orbit plotting, among others.  It focuses on interplanetary
applications, but can also be used to analyze artificial satellites in
Low-Earth Orbit (LEO).")

    (description
     "@acronym{POPPY, Physical Optics Propagation in Python} is a Python package that
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.")

@item generation of WCS-compliant and @code{SWarp}-compatible FITS image headers
in output
@item automatic grouping of catalogues on the sky

@item automatic determination of scale, position angle, flipping and coordinate
shift using fast pattern-matching

     "This package provides an astronomical image processing tool - SIRIL.  It
is specially tailored for noise reduction and improving the signal/noise ratio
of an image from multiple captures, as required in astronomy.  SIRIL can align
automatically or manually, stack and enhance pictures from various file
formats, even image sequence files (films and SER files).  It works well with
limited system resources, like in embedded platforms, but is also very fast
when run on more powerful computers and provides conversion to FITS from a
large number of image formats.")
