The tilt of the cleaved end face measured by the splicer's cameras before arcing. Good cleaves come in under 0.5 degree, and most splicers are set to reject anything above about 1 to 1.5 degrees because an angled pair of ends leaves a gap and a weak, lossy splice. Fiber type, blade condition and tension all affect it.
