Mass fraction of metals fZ produced in situ for an instantaneous burst (blue lines), a burst with exponential decay (red lines), and a continuous star formation model (green lines) as a function of optical colors (left panels) and time (right panels). Each model for both Clump1 (top panels) and Clump2E (bottom panels) is normalized as to produce an apparent magnitude μB = 29 at any time after star formation switches on. The dashed lines indicate the maximum BV optical color of the clumps, and the dotted line ﹩{f}_{Z}^{\max }﹩, the highest value of fZ compatible with BV.
