Inferred fractional change of rotation period during the glitch, ΔP/P, obtained by equating the rotational energy gained during the glitch, ΔE_rot, to the energy of the burst, for globally neutral (left panel) and locally neutral (right panel) NSs. In this example the NS obeys the GM1 EOS. The gray-shaded area corresponds to the value of | ΔP | /P in the observed glitch of PSR J1846–0258 in June 2006 (Kuiper & Hermsen 2009).
