Abstract
Local Thermodynamic Equilibrium (LTE) is known to be a useful simplifying assumption when computing line-blanketed model stellar atmospheres and synthetic spectra. Element abundance adjustment can optimise agreement between a synthetic and an observed spectrum, providing a useful technique for abundance determination when spectrum lines are blended. Interactive abundance adjustment techniques are proposed as a means of minimising the effort involved in using LTE spectrum synthesis to obtain abundances for several elements in a large sample of stars.
