Got permission from Ingo to use his response in the copyright file and the relevant portion now looks like this: Files: sct.c Copyright: 2016 Ted Unangst <tedu@openbsd.org> whitepoints data copyright 2013 Ingo Thies <ithies@astro.uni-bonn.de> License: public-domain-sct and public-domain-colorramp License: public-domain-sct public domain, do as you wish License: public-domain-colorramp I have calculated the table by following mathematical rules of color integration and conversion from the CIE 1931 color space to sRGB. . I doubt that a numerically computed color table is copyrightable at all (in contrast to the actual software implementation). However, if it is indeed copyrightable, I have no problem with releasing it into the public domain. Is there a better way to indicate copyright over a portion of a file? Is this clear enough?
