Scientific paper

Using ATLAS9 model atmospheres and additional spectroscopic data from the Kitt Peak coude-feed telescope obtained with a 3000-pixel-long CCD, camera 5, and grating A, we extend fine analyses of the B and A stars, gammaGem, HD 60825 and 7Sex. In addition, we study two moderately sharp-lined middle B stars, HR 1397 and 2154, whose elemental abundances we find to be generally within the range of values seen for superficially normal, main-sequence stars of similar temperatures.
