TOPCAT is an interactive graphical viewer and editor for tabular data.[2] It is open-source software, originally written and still maintained by Mark Taylor, an astrophysicist from Bristol University. Although a general purpose tool capable of handling large datasets its specialist application area is astronomy where it can utilitise data stored in the FITS digital file format.[3]

History[edit | edit source]

The project was initially developed in 2003 with funding from the Starlink Project and been funded by various others projects since.[4] The Acronym TOPCAT derives from Tool for OPerations on Catalogues And Tables.[5]

Features[edit | edit source]

Written in Java, TOPCAT can be used both standalone and within a web browser.[6]:1 It is suitable for use as a graphical viewer and data editor of tabular data from FITS and other sources.[7]

While TOPCAT is unable to visualise catalogues as a set of vectors it does have capabilities to explore correlations in two and three dimiesional scatter plots.[8]

Uses[edit | edit source]

Applications using TOPCAT include MultiDark, a database for results from cosmological simulations.[9]

Alternatives[edit | edit source]

Muna, in his 2016 paper "Introducing Nightlight: A New FITS Viewer", observes that SAOImage DS9, TOPCAT and fv are the most common tools used to view FITS files.[10]

Related software[edit | edit source]

The STILTS application complements TOPCAT with similar capabilities but is considered a steeper learning curve however STILTS does have the advantage of being able to be scripted.[11]
