OMP reconstructions with the pixel basis of the object from Fig. 7a, radio emission from 3C75, simulated with measurements from a URA in a) (RE = 2.89 × 10-4), an NRA of SD = 0.18 in b) (RE = 5.4617), the “Y” array in c) (RE = 0.840), and the YOPP array in d) in the under-resolved case when . All pixel brightness values in the object and reconstructions are normalized by the object’s maximum pixel brightness value, to lie on [0, 1]. Image a) can be found at http://images.nrao.edu/29 (courtesy of NRAO/AUI and F.N. Owen, C.P. O’Dea, M. Inoue, and J. Eilek). Original versions of these figures appeared in Fannjiang (2011).
