Early aquisition WFPC images were made in August of 1994 via proposal 5365. In this proposal, the FOS red and blue sides will be used to obtain spectra of 3 individual knots in the remnant to test emission mechanisms and derive elemental abundances. The peakup found the star at dwell point 7, and the spectra show a noisy continuum with several strong emission lines. There was a 3 second recentering during observation 04. The stability of the FOS Blue side wavelength scale and spectral locations will be measured.
All observations are internals.
The objective is to determine the Deuterium-Hydrogen ratio in the interstellar medium in the line of sight to those stars. Lines of MgII and FeII will also be observed, in order to find the different velocity components of the medium. The spectra have plenty of signal with several strong features. There was one 3 second recentering during observation 07.
