C.1 Acknowledgements

The initial development of STILTS was done under the UK's Starlink project (1980-2005, R.I.P.). Since then it has been supported by grant PP/D002486/1 from the UK's Particle Physics and Astronomy Research Council, the VOTech project (from EU FP6), the AstroGrid project (from PPARC/STFC), the AIDA project (from EU FP7), grants ST/H008470/1, ST/I00176X/1, ST/J001414/1 and ST/L002388/1 from the UK's Science and Technology Facilities Council (STFC), the GAVO project (BMBF Bewilligungsnummer 05A08VHA), the European Space Agency, and the EU FP7-2013-Space project GENIUS. All of this support is gratefully acknowledged.

Apart from the excellent Java 2 Standard Edition itself, the following external libraries provide important parts of STILTS's functionality:

• JEL (GNU) for algebraic expression evaluation
• PixTools (Fermilab EAG) for HEALPix-based celestial sphere row matching
• iText (1T3XT BVBA) for PDF output
• EPSGraphics2D (Jibble) for encapsulated postscript output
• MOC (CDS) for Multi-Order Coverage map manipulation
• ADQL (CDS) for ADQL parsing in TAP query preparation
• nom.tam.fits (NASA) for parts of FITS I/O
• Skyview in a Jar (NASA) for sky axis drawing
• JLaTeXMath (Scilab) for LaTeX typesetting in plots
• GifEncoder (Acme) for GIF output
• HTM (Sloan Digital Sky Survey) for HTM-based celestial sphere row matching (now deprecated within STILTS)

Many people have contributed ideas and advice to the development of STILTS and its related products. I can't list all of them here, but my thanks are especially due to the following:

• Malcolm Currie (Starlink, RAL)
• Clive Davenhall (Royal Observatory Edinburgh)
• Peter Draper (Starlink, Durham)
• David Giaretta (Starlink, RAL)
• Clive Page (AstroGrid, Leicester)
