Top: maximum (50 kADU) relative amplitude of the brighter-fatter effect in DECam. The relative slope becomes steeper when the IQ improves. Bottom: maximum amplitude of the variation of PSF shape in the various filters. The brighter-fatter effect seems achromatic, and the linear IQ increase seems fairly independant of IQ.

This figure is made of several images, please see below:
