Name        : ast
Product     : Fedora EPEL 7
Version     : 7.3.4
Release     : 1.el7
URL         : http://starlink.jach.hawaii.edu/starlink/AST
Summary     : A Library for Handling World Coordinate Systems in Astronomy
Description :
The AST library provides a comprehensive range of facilities for attaching
world coordinate systems to astronomical data, for retrieving and interpreting
that information and for generating graphical output based on it. It's main
selling points are:

* Ease of use.
* Facilities for generating plots of generalized non-linear, potentially
  discontinuous 2-D or 3-D coordinate systems, with detailed control of the
  appearance of the plot.
* Facilities for converting transparently between different coordinate
  systems, including a wide range of celestial, spectral and time coordinate
  systems.
* Facilities for searching a general collection of connected coordinate
  systems for a coordinate system with any given set of characteristics.
* Allows code for handling WCS information to be written in a general way
  without regard to the specific nature of the coordinate systems being
  handled (i.e. whether they represent sky positions, spectral positions,
  focal plane positions, pixel positions, etc).
* Flexible system for saving and retrieving WCS information, including (but
  not limited to) a range of different popular FITS descriptions.
* Written in C but has interfaces for C, Fortran, Java (via JNI), Perl, and
  UNIX shell.
* Extensive documentation.

Update Information:

Update to 7.3.4, change:
- By default, the simplification of Polygons no longer checks that the edges are not bent by the simplification. A new attribute, SimpVertices, can be set to zero in order to re-instate this check.
- The Polygon class has a new mathod, astConvex, that returns a Polygon representing the shortest polygon (i.e. convex hull) enclosing a specified set of pixel values within a supplied array.
