Description
The Parkes Multibeam (PM) Pulsar Survey uses the 20 cm multibeam receiver system and multibeam filter banks, digitizer and data-acquisition system to survey a region within |b| < 5 degrees in the inner Galactic plane for pulsars, many of which will be young and/or short-period. This survey is a factor of 7 times more sensitive to young and distant pulsars than that of Johnston et al. (1992, MNRAS, 255, 401) which detected 100 pulsars. The present source list contains pulsars that have been newly discovered in the course of this survey. The PM Survey is specifically targeted for (i) obscured regions of the Galactic plane, (ii) young pulsars,and (iii) binary pulsars with massive companions. As of August 1999, analysis of about 50% of the total expected data to be collected has resulted in the confirmed detection of over 400 new pulsars (an increase of more than 50% of the known population). Here are some of the features of the PM Survey: <pre> Survey Area: -260 < l < 50 deg , -5 < b < 5 deg Center Frequency: 1374 MHz Bandwidth: 288 MHz (96 channels x 3 MHz per channel x 2 polarizations) Sampling Rate: 0.25 ms x 1 bit per channel Integration Time: 35 min per pointing (13 beams per pointing) Data Storage: DLT tape (about 35 GB per tape) Sensitivity: about 7 times better than previous 400 MHz surveys </pre> This database table was initially created by the HEASARC in December 2001 and revised in March 2002. The contents of the table are based on the file <a href="http://www.atnf.csiro.au/research/pulsar/pmsurv/pmpsrs.db">http://www.atnf.csiro.au/research/pulsar/pmsurv/pmpsrs.db</a> on the authors' website. The HEASARC table will be updated on a weekly basis whenever the original table is updated. This is a service provided by NASA HEASARC .
