General astronomical data analysis and Hubble Space Telescope data calibration

Project description

stsci_python is a library of Python routines and C extensions that has been developed to provide a general astronomical data analysis infrastructure. Primary development has been done to support Hubble Space Telescope (HST) data calibration and analysis needs based on general purpose libraries from the environment. Several of the packages, though, can also be used to support data processing of astronomical data. It includes the following:

PyRAF
an environment for running IRAF tasks without using the IRAF CL
PyFITS
(released separately as well) used to read FITS images and tables into numpy or numarray objects and to manipulate FITS headers. See http://www.stsci.edu/institute/software_hardware/pyfits for full details.
pysynphot
a synthetic photometry package (still in development) designed to replace IRAF’s STSDAS.SYNPHOT. It is suitable for library or interactive use.
DrizzlePac
a package for aligning and combining STScI images. Full documentation available at http://drizzlepac.stsci.edu .
acstools
tasks for post-calibration processing of HST ACS images
calcos
calibration software for HST Cosmic Origins Spectrograph’s(COS) data
costools
tasks for post-calibration processing of HST COS data
fitsblender
general purpose package for merging FITS headers from multiple images into a single header
nictools
tasks for post-calibration processing of HST NICMOS images
stistools
tasks for post-calibration processing of HST STIS images
wfc3tools
tasks for post-calibration processing of HST WFC3 images
wfpc2tools
tasks for post-calibration processing of HST WFPC2 images
stsci.tools
provides TEAL interface for defining a GUI for running Python tasks based on configobj for managing parameters
imagestats
perform image statistics with sigma-clipping ierations
numdisplay
task to visualize numpy array objects using image display tools like ds9 and ximtool through IRAF’s IIS protocol
