We have collected together many of the astronomical applications
developed as IRAF tasks at the Space Telescope European Coordinating
Facility (ST-ECF) into a new 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.
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 a ``quicklook'' grism
spectral extraction tool, originally for HST STIS data, are also included.
