HASH: the Hong Kong/AAO/Strasbourg H-alpha planetary nebula database

Understand

By incorporating our major recent discoveries with re-measured and verified contents of existing catalogues we provide, for the first time, an accessible, reliable, on-line SQL database for essential, up-to date information for all known Galactic PNe.

• We have attempted to: i) reliably remove PN mimics/false ID's that have biased previous studies and ii) provide accurate positions, sizes, morphologies, multi-wavelength imagery and spectroscopy.
• We also provide a link to CDS/Vizier for the archival history of each object and other valuable links to external data.
• With the HASH interface, users can sift, select, browse, collate, investigate, download and visualise the entire currently known Galactic PNe diversity.
