The Astropy Project is a collection of software packages written in the Python programming language and designed for use in astronomy.〔 〕 The software is a single, free, core package for astronomical utilities due to the increasingly widespread usage of Python by astronomers, and to foster interoperability between various extant Python astronomy packages.〔 〕 Astropy is included in several large Python distributions; it is part of package managers for Linux and OS X,〔 (【引用サイトリンク】url=http://packages.debian.org/testing/python/python-astropy )〕〔 (【引用サイトリンク】url=https://trac.macports.org/browser/trunk/dports/python/py-astropy/Portfile )〕〔 (【引用サイトリンク】url=http://pdb.finkproject.org/pdb/package.php/astropy-py33 )〕 the Anaconda Python Distribution, Enthought Canopy and Ureka.〔 (【引用サイトリンク】url=http://ssb.stsci.edu/ureka/source/ )〕 == Core functionality == Core data structures and operations * generalized container classes for representing gridded and tabular data as multidimensional arrays or tables〔(【引用サイトリンク】 url=http://atpy.readthedocs.org/ )〕 * unit and physical quantity conversions * physical constants specific to astronomy * celestial coordinate and time transformations * world coordinate system (WCS) support, implementing PyWCS, the Python wrapper to WCSLIB. WCSLIB is a C Library which implements the WCS standard in the Flexible Image Transport System (FITS) standard. File I/O * FITS files, implementing the former standalone PyFITS interface〔(【引用サイトリンク】url=http://www.stsci.edu/institute/software_hardware/pyfits/ )〕 * Virtual Observatory (VO) tables * common ASCII table formats, e.g. for online catalogues or data supplements of scientific publications * Hierarchical Data Format (HDF5) files Computational utilities * framework for cosmology transformations and conversions * toolset for statistical analyses 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Astropy」の詳細全文を読む スポンサード リンク
