ROBOSPECT: Automated Equivalent Width Measurement

TL;DR

ROBOSPECT is an automated tool designed to accurately measure and deblend line equivalent widths in both absorption and emission spectra, validated against simulations and manual measurements.

Contribution

The paper introduces ROBOSPECT, a novel automated code that improves the efficiency and accuracy of spectral line equivalent width measurements.

Findings

ROBOSPECT's measurements match synthetic and manual results within expected scatter.

The tool performs well across different signal-to-noise ratios.

It effectively deblends overlapping spectral lines.

Abstract

We present ROBOSPECT, a new code to automatically measure and deblend line equivalent widths for both absorption and emission spectra. We test the accuracy of these measurements against simulated spectra as well as manual equivalent width measurements of five stellar spectra over a range of signal-to-noise values and a set of long slit emission spectra. We find that ROBOSPECT accurately matches both the synthetic and manual measurements, with scatter consistent with the expectations based on the data quality and the results of Cayrel (1988).
