Anchors
AN archive of Chandra Observations of Regions of Star formation
The goal of ANCHORS is to provide a uniform (not necessarily optimal) database for the comparison of data from different clusters.
This page is a prototype under development. Choose an observation from the list below to view the data and analysis available, including multi-band images (Chandra, 2MASS, DSS), spectral fits, light curves, and links to data archives and references.
