TABLES/STSDAS v3.5 and STScI_PYTHON v2.3 now available

******************************************************* TABLES/STSDAS v3.5 and STSCI_PYTHON v2.3 NOW AVAILABLE ******************************************************* The Astronomy Tools and Applications Branch of the Space Telescope Science Institute wishes to announce the availability of version 3.5 of the Space Telescope Science Data Analysis Software (STSDAS). Concurrent with the STSDAS release, we have also released v3.5 of the TABLES external package. Both of these packages are layered upon IRAF as external packages; it is therefore necessary to obtain and install IRAF (from http://iraf.noao.edu) before installing TABLES and STSDAS. STSDAS is linked against libraries in TABLES, so TABLES must be installed before STSDAS. STSDAS includes some Python-based tasks; running these requires the STScI Python Libraries to be installed (all the non-Python tasks can be used in the traditional way and do not require Python or the STScI Python libraries). These tasks can only be run from PyRAF using standard IRAF CL task syntax, or within Python scripts using Python syntax. The Astronomy Tools and Applications Branch of STScI also wishes to announce the availability of version 2.3 of STSCI_PYTHON. This release includes updated versions of Multidrizzle and CALSTIS as used by the HST ACS pipeline, along with new versions of aXe, saaclean, numarray, PyFITS and PyRAF. A new task, puftcorr, was also added for NICMOS data reduction. Use of the Python tasks requires upgrading to this version of STSCI_PYTHON. WHERE TO OBTAIN THIS SOFTWARE STSDAS/TABLES v3.5 can be downloaded from the STSDAS web site http://www.stsci.edu/resources/software_hardware/stsdas/download Installation instructions are available on the web site. Precompiled binaries also exist for some of the ports supported by NOAO, including Sun Solaris, RedHat Linux and Mac OS X. STSCI_PYTHON v 2.3 be downloaded from the PyRAF web site http://www.stsci.edu/resources/software_hardware/pyraf/stsci_python/ current/download Installation instructions are available from the PyRAF web site. Please contact us through e-mail (help(a)stsci.edu), by telephone at (410) 338-1082. -- Warren J.

PyFITS 1.1 "alpha" release -- NUMPY now supported
by Christopher Hanley 24 মার্চ, 2006

24 মার্চ, 2006

------------------ | PyFITS Release | ------------------ Space Telescope Science Institute is pleased to announce the "alpha" release of PyFITS 1.1. This release includes support for both the NUMPY and NUMARRAY array packages. This software can be downloaded at: http://www.stsci.edu/resources/software_hardware/pyfits/Download The NUMPY support in PyFITS is not nearly as well tested as the NUMARRAY support. We expect that you will encounter bugs. Please send bug reports to "help(a)stsci.edu". We intend to support NUMARRAY and NUMPY simultaneously for a transition period of no less than 1 year. Eventually, however, support for NUMARRAY will disappear. During this period, it is likely that new features will appear only for NUMPY. The support for NUMARRAY will primarily be to fix serious bugs and handle platform updates. ----------- | Version | ----------- Version 1.1a1; March 24, 2006 ------------------------------- | Major Changes since v1.0.1 | ------------------------------- * Added support for the NUMPY array package * Use of the NUMPY or NUMARRAY array package is controlled through the use of an environmental variable (NUMERIX) * Access to private methods and attributes is now through the pyfits.core module * Now installed as a packaged instead of a singe file ------------------------- | Software Requirements | ------------------------- PyFITS Version 1.0 REQUIRES: * Python 2.3 or later * NUMPY or NUMARRAY --------------------- | Installing PyFITS | --------------------- PyFITS 1.0 is distributed as a Python distutils module. Installation simply involves unpacking the package and executing % python setup.py install to install it in Python's site-packages directory. Alternatively the command %python setup.py install --local="/destination/directory/" will install PyFITS in an arbitrary directory which should be placed on PYTHONPATH. Once numarray or numpy has been installed, then PyFITS should be available for use under Python. ----------------- | Download Site | ----------------- http://www.stsci.edu/resources/software_hardware/pyfits/Download ---------- | Usage | ---------- Users will issue an "import pyfits" command as in the past. However, the use of the NUMPY or NUMARRAY version of PyFITS will be controlled by an environment variable called NUMERIX. Set NUMERIX to 'numarray' for the NUMARRAY version of PyFITS. Set NUMERIX to 'numpy' for the NUMPY version of pyfits. If only one array package is installed, that package's version of PyFITS will be imported. If both packages are installed the NUMERIX value is used to decide which version to import. If no NUMERIX value is set then the NUMARRAY version of PyFITS will be imported. Anything else will raise an exception upon import. --------------- | Bug Reports | --------------- Please send all PyFITS bug reports to help(a)stsci.edu ------------------ | Advanced Users | ------------------ Users who would like to follow the "bleeding" edge of PyFITS development can retrieve the software from our SUBVERSION repository hosted at: http://astropy.scipy.org/svn/pyfits/trunk We also provide a Trac site at: http://projects.scipy.org/astropy/pyfits/wiki -- Christopher Hanley Systems Software Engineer Space Telescope Science Institute 3700 San Martin Drive Baltimore MD, 21218 (410) 338-4338
