Parkes Multibeam Survey: New Pulsar Catalog from the Galactic Plane

A catalog of over 400 newly discovered pulsars from the Parkes Multibeam (PM) Pulsar Survey. The survey, conducted by NASA HEASARC, targeted the inner Galactic plane and was about 7 times more sensitive to young and distant pulsars than a previous 1992 survey. The database table was created in December 2001 and is updated weekly based on the authors' source file.

Use Cases

• Studying the population and distribution of young pulsars based on the survey's targeted focus.
• Analyzing pulsar characteristics in obscured regions of the Galactic plane as described in the survey goals.
• Identifying candidate binary pulsars with massive companions based on the survey's specific targeting.
• Comparing pulsar discovery sensitivity against previous 400 MHz surveys based on the stated 7-fold improvement.

Strengths

• Contains over 400 confirmed new pulsars, representing a more than 50% increase in the known population at the time.
• Survey sensitivity is described as about 7 times better than previous 400 MHz surveys.
• Data is updated on a weekly basis when the original source table is updated.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality requires manual inspection after download.
