IV. Jornadas de Astrofisica Estelar, Tucumán, Arjantin, 22 - 24 Haziran 2022, ss.22-32
The most senior authors began their research on stellar abundances when the basic analysis
techniques were tracing photographic plates with a microdensitometer, converting them to
scientific charts and using the curve-of-growth technique. Later improvements involved
digitizing and measured the spectra and using computer graphics techniques and model
atmospheres. Still later, Reticon detectors and then charged couple devices (CCDs) became the
detectors of choice.
