		| Abstract: | 
		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. |
