Scientific paper

We propose observations of the UV spectra of two low-mass X-ray binaries {Sco X-1 and Cyg X-2} with existing Chandra X-Ray Observatory {CXO} data. From the X-ray data we will measure total {phase-independent} column densities of O, Ne, and Fe. From the UV data we will determine gas-phase column densities of H and O. The data in conjunction will allow us to make unique measurements of the total interstellar abundances of oxygen, neon, and iron, and direct measurements of the dust-phase abundances of O and Fe.;
