Abstract The aim of this proposal is to verify the wavelength calibrations obtained using pre -COSTAR observations and compare the photometric response between a line source and a continuum source from the DQE proposal. This will be accomplished by observing a source known from IUE spectra to contain a large number of emission lines in the UV and compare the resulting computed wavelengths for the lines that are detected with the IUE spectra. This will allow for refinement of the dispersion curve which was effectively determined from very few lines. This level of calibration would then allow for reduction of objective prism observations and subsequent scientific comparison of FOC results with ground-based and IUE spectra which should which should be free of systematic errors. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Description of proposed observations. Important characteristics of the objective prisms are the dimensions and displacements of the dispersed images on the FOC detectors. The following table lists the anticipated lengths and average offsets: length mean offset FUV/96 lambda 1200-lambda 6000 2.5 arcsec 4.8 arcsec NUV/96 lambda 1850-lambda 6000 8.0 arcsec 1.6 arcsec The objective prisms will be used as low dispersion spectrographs to provide spectra of a wavelength standard. The observations will use the 256X1024 format so that the NUVOP spectra are not cut off at either the UV or red end. Thus, the stars must be well centered in the X-direction. The direct images will be offset by the same amount as the prism images so that the star's absolute position can be precisely known allowing for accurate zero-point for the wavelength calculations of the spectra. ------------------------------------------------------------------------------------ 11.
