The Extended Chandra Deep Field-South Survey

This WWW site presents results from the Extended Chandra Deep Field-South survey. This survey is composed of four 250 ks Chandra ACIS-I observations flanking the original Chandra Deep Field-South. The total solid angle covered by these observations is about 1100 sq. arcmin.
