hello I have put data (locations and times) in an additional page: http://legault.perso.sfr.fr/STS-134_data.html One raw file (12-bit fits) is available here: http://legault.perso.sfr.fr/sts-134_110529_f1819.fits regards At 23:44 05/06/2011, Thierry Legault wrote: >Justin, although I did not want to overload the >e-mail and the web page (most visitors don't >care about detailed info such as observation >site coordinates), I can provide anything, there >is no secret.
