TOPCAT was initially (2003-2005) developed under the UK
Starlink project
(1980-2005, R.I.P.). From July 2005 until June 2006, it was supported
by grant PP/D002486/1 from the UK's
Particle Physics and Astronomy Research Council.
Maintenance and development has been funded from July 2006 until
December 2007 by the
European VOTech project
within the UK's AstroGrid,
and directly from AstroGrid funding beyond that.
Inspiration for many of TOPCAT's features has been taken from the
following pre-existing tools:
Apart from the excellent Java 2 Standard Edition itself,
the following external libraries provide important parts of TOPCAT's
functionality:
-
JEL
(GNU) for algebraic expression evaluation
-
PixTools
(Fermilab EAG) for HEALPix-based celestial sphere row matching
-
HTM
(Sloan Digital Sky Survey) for HTM-based celestial sphere row matching
(now deprecated within TOPCAT)
-
Ptplot
(Ptolemy) for axis plotting
-
EPSGraphics2D
(Jibble) for encapsulated postscript output
-
GifEncoder
(Acme) for GIF output
-
IVOA FITS Package
(Sloan Digital Sky Survey) for simple (non-SoG) display of FITS images
-
BrowserLauncher for launching default web browser
