stsci_python is a library of Python routines and C extensions that has been developed to provide a general astronomical data analysis infrastructure. It includes the following:
- PyRAF, an environment for running IRAF tasks without using the IRAF CL
- DrizzlePac, a task for combining dithered STScI images
- PyFITS, used to read FITS images and tables into numpy or numarray objects and to manipulate FITS headers
- pysynphot is a synthetic photometry package (still in development) designed to replace STSDAS.SYNPHOT. It is suitable for library or interactive use.
- Numdisplay, used to visualize numpy array objects using image display tools like ds9 and ximtool
stsci_python is now available on the Python Package Index, for installation with pip or easy_install. There are some complications, so please read the Installation Instructions
