Permission (Reusing this file) |
I sent an email to Pierre.Fernique@astro.unistra.fr to ask about PUBLIC Domain use of Aladin skyplots. He emailed back that "First of all, thanks to use Simbad and Aladin to generate your sky plots. There is absolutely no problem to use them for Wikipedia pages. A citation of Aladin would be appreciated. Best regards Pierre Fernique" |
The J2000.0 position of 2U 1728-16 is almost exactly 2' south-southwest of the tip of the red arrow, specifically 2' straight down from this tip.
