Introduction

We have collected together many of the astronomical applications developed as Iraf tasks at the Space Telescope European Coordinating Facility (ST-ECF) into an Iraf layered package called "stecf". This package contains several subpackages. One contains a variety of image restoration algorithms including multiple channel and photometric variants of the Richardson Lucy method. In addition a wholly new package ("impol") for the reduction of polarimetric imaging from HST (and ground-based instruments) is made available for the first time. Software for the post-pipeline processing of HST NICMOS data, with particular emphasis on the association and pre-processing of images to be used for grism spectral extraction, and finally a general purpose grism spectral extraction tool are also included.

The Version 1.2 released in September 2001 also includes the new SPECRES package for spectroscopic data restoration.

The Version 1.5 released in Summer 2003 includes major upgrades to the SPECRES package as well as newer version of the DRIZTOOLS.
