One new pulsar, PSR J15283146, has a 61 ms spin period and a massive white dwarf companion. Like many recycled pulsars with heavy companions, the orbital eccentricity is relatively high (0.0002), consistent with evolutionary models that predict less time for circularization. The four remaining pulsars have short spin periods (3 ms < P < 6 ms); three of these have probable white dwarf binary companions and one (PSR J20101323) is isolated. PSR J16003053 is relatively bright for its dispersion measure of 52.3 pc cm3 and promises good timing precision thanks to an intrinsically narrow feature in its pulse profile, resolvable through coherent dedispersion. In this survey, the recycled pulsar discovery rate was 1 per 4 days of telescope time or 1 per 600 deg2 of sky. The variability of these sources implies that there are more millisecond pulsars that might be found by repeating this survey. 2007 published The Astrophysical Journal 656 1 University of Chicago Press 408-413 TRUE 1538-4357 http://www.journals.uchicago.edu/doi/abs/10.1086/509312 4802 3 4047 1 application/pdf en staffonly cc_utas
