Stumm, Lang, and I gathered some (heuristic) evidence for sources in the region of M42 (the Orion Nebula) using images submitted to the Flickr pool. The image below shows in transparent blue symbols the detected sources in the Flickr images in a tiny patch in the nebula. We take it from this that the amateur data do have highly redundant (and therefore reliable) information about many sources.
Hi David,
ReplyDeleteI don't get something. You mean, sources of what?
