PMPULSAR - Parkes Multibeam Survey New Pulsar Catalog
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:
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
This catalog was obtained from the PM Survey website at
http://www.atnf.csiro.au/research/pulsar/pmsurv/. The results of the PM
Survey have been published in an ongoing series of papers:

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
http://www.atnf.csiro.au/research/pulsar/pmsurv/pmpsrs.db on the authors'
website. The HEASARC table will be updated on a weekly basis whenever the
original table is updated.
The HEASARC has added three derived parameters to this table which were not
present in the original catalog as obtained from the ATNF: log_b_surf,
log_age and log_e_dot. See the parameter descriptions for the formulae used
to calculate these parameters.
A small number of the new pulsars discovered in the PM Survey have been
discovered to be in binary systems. A table with information on the binary
parameters can be found in the file

The log10 of the characteristic age T in years (set to null
if the period derivative Period_dot is not positive), calculated using the
standard relation T = (0.5*Period/Period_dot).
The log10 of the surface magnetic field strength B_surf in
Gauss (set to null if the period derivative Period_dot is not positive),
calculated using the standard relation
B_surf = 3.2 x 10^19 x (Period x Period_dot)^0.5.
The log10 of the total energy loss rate E_dot in erg/s
(set to null if the period derivative Period_dot is not positive),
calculated using the standard relation
E_dot = 4 x pi^2 * I * (Period_dot/Period^3), and an assumed value for the
moment of inertia I of 10^45 gm cm^2.
