Receipt: # 2-5 0 ----- Attempting Submission 1 (Fri Jul 01 11:00:01 GMT 2016) ----- Stellar atmospheres are prime laboratories to determine atomic properties of highly ionized species. Since reliable metal opacities are crucial ingredients of many astrophysical simulations, we propose to exploit STIS's spectroscopic capabilities to obtain high-resolution, high-S/N spectra of three hot subdwarf stars that exhibit extremely high iron-group (calcium to nickel) abundances and, thus, are ideal objects to identify even weak spectral lines of these species. The precise spectral analysis by advanced non-LTE model-atmosphere techniques allows to determine photospheric properties accurately and subsequently derive relative weighted oscillator strengths of iron-group lines. This will establish an important benchmark test for available atomic-line lists of iron-group elements for ionization stages III to VI. Short-slit (0.2"x0.2") medium-dispersion UV spectroscopy of three relatively bright , isolated sdOB stars in the STIS/FUV-MAMA configuration with grating E140M to cover the wavelength range 1150-1700 A. We used the STIS ETC (version 24.2) to determine the exposure times necessary to achieve S/N 30 - 50 in the complete wavelength range. From our experience with previous HST/STIS data analyses, this S/N is necessary for reliable line-profile analysis. To achieve the maximum S/N, we use the complete orbit.
