Systematics in metallicity gradient measurements. I. Angular resolution, signal to noise, and annular binning

Yuan, TianTian; Kewley, Lisa; Rich, J


With the rapid progress in metallicity gradient studies at high redshift, it is imperative that we thoroughly understand the systematics in these measurements. This work investigates how the [N II]/Hα-ratio-based metallicity gradients change with angular
