... The near-UV prism (NUVOP) transmits only above 1600 with a wavelength dispersion / around 100 at 2500 . ... The wavelengths determined from objective prism spectra using these dispersion curves should have a / error of <1% for f /96 spectra. ... 4000 . ... Overall, photometry of objective prism spectra should have errors of about 10% or less for wavelengths below 4000 for NUVOP spectra and below 2500 for FUVOP spectra, provided that the position of the undispersed target is known to within a pixel. ...

Extracting spectra from a large number of NICMOS grism images requires a convenient interactive tool which allows a user to manipulate direct/grism image pairs. ... NICMOSlook and Calnic-C are two programs that were designed to take advantage of the fact that the NICMOS grism mode typically consists of taking both a direct and a grism image. ...

Extracting spectra from a large number of NICMOS grism images requires a convenient interactive tool which allows a user to manipulate direct/grism image pairs. ... The direct image is used to locate objects of interest, to find the position of the appropriate spectra in the grism image, to determine the optimal extraction technique to use, and to calibrate the wavelength range of the extracted spectra. ...
