The NICMOS GRISM Mode
Abstract
In addition to broad band, medium band and wide band filter sets, the Near-Infrared Camera Multi-Object Spectrometer (NICMOS) Camera 3 (NIC3) filter wheel contains three grisms. These grisms provide low-resolution slitless spectroscopic capabilities. Servicing Mission Observatory Verification (SMOV) data verified basic properties of the grisms. Two weeks of grism data with the best possible focusing for NIC3 have been collected in late July and early August 1997. Spectra have been extracted from all visible sources in that data set using software developed at the Space Telescope - European Coordinating Facility. No emission lines or absorption lines are found in any of the objects.
