Ovalbumin phosphopeptide spectra. The spectrum on top is from a triply charged peptide with a mass error of 0.19 ppm and a PEP of 1.2e-178. The spectrum below is shows the fragments of a doubly charged peptide with a mass error of 0.40 ppm and a PEP of 8.9e-62. Y-ions are shown in red, b-ions in blue, and fragments with neutral loss of ammonia or water are in orange. A few additional annotations of major fragments not annotated automatically are in black. Asterisks indicate loss of the phospho group. These fragments are important for site location
