WHAT DOES CO-SIGNING THE WHITE PAPERS IMPLY? Co-signature on the white paper implies support for the science vis-a-vis the Astro2010 committee. It implies that your name will appear as a co-signer in the paper submitted to the Astro2010 committee and in the version submitted to astro-ph/ Co-signature is different from coauthorship on science papers. The white papers are not regular scientific papers for which intellectual contribution is required in order to be a coauthor. We encourage everyone to read and co-sign the white papers regardless of the level of contribution made to the writing of the papers.
