Eccentricity as a function of orbital period for binary radio pulsars in globular clusters. Colours are used to indicate γ of the cluster in which the pulsar resides, symbols to indicate the companion mass. For the outcome of recycling by a (sub)giant donor one expects P_b ≳ 1 d and 0.1 < M_c/M_⊙ < 0.44; such systems in the Galactic disc are shown in gray, and the expectation values for the eccentricity according to Eq. (4) and ten times this value, are shown as dotted lines. Eccentricies 0.0, for which no upper limits have been specified, are shown at the bottom (with smaller symbols to avoid overlap). Data from http://www.naic.edu/~pfreire/GCpsr.html
