stecf.nictools - NICMOS GRISM Tools

The stecf.nictools package http://www.stecf.org/instruments/nicmos/nictools/ is a collection of IRAF cl scripts to group, process and co-add NICMOS direct and grism images. It was written to help the processing of NICMOS grism images after they have been calibrated with the STScI pipeline calnica and before spectra are extracted with the ST-ECF software NICMOSlook or calnicc. It is also useful for simple co-adding (shift and add) of direct images.
