ST-ECF NICMOS Grism Software

Software for Grouping and Procssing of Grism + Direct Images

NICTOOLS A set of IRAF scripts to help to create "association files" for grism and direct images, process those images and co-add them. Also useful for pure direct image observations.

Spectrum Extraction Software

NICMOSlook Interactive tool to extract spectra from grism images or analyze spectra extracted by other means. Implemented as IDL widget, needs IDL running under X.

CalnicC A now obsolete program to extract spectra from grism images and matching direct images without human intervention. Not supported any longer and not recommended for NICMOS. This program is being replaced by a new version of the aXe extraction software.

Spectrum Deconvolution Software

Slitless grism spectroscopy results in confused spectra in crowded field and for extended objects. When several such images are taken at different role angles, it is in principle possible to deconvolve such confused images. Experimental software to solve this problem has been developed at ST-ECF, based on full 3d deconvolution ( GRISMdecon.).
