Why are there more object images than SED plot points?

  • DNiergarth by DNiergarth

    I've been doing this for a few months now and it struck me that there are ten images per folder but only seven points on the SED!? Does anyone have an explanation? Are the three missing images falling on the curve of the SED?

    Great question. Most of these objects do not have sufficiently reliable optical photometry to create a good SED plot point. 2MASS and WISE do exist for almost all of these objects and are very reliable. However, one thing we'd like to do down the road is to incorporate better optical photometry such as from the Sloan Digital Sky Survey and other projects. It may be that we will be able to get some more information that way.
