Naming convention ----------------- First character: K = (Kogan) ring type array C = (Conway) spiral type array Second character: A, C or E, denoting resolution of array Characters 3-5: Member of SIL- M51, CYG, MAR, SDC or MPD Characters 6 and 7: SN (snapshot) or track, e.g. _4 for 4hr track Characters 8-10: signed declination Characters 11 and 12: Wavelength, e.g. _1 or _3 for 1 and 3mm respectively or b7 corresponding to ALMA band 7 frequency (345GHz)
Images CLEANed for 10,000 iterations.
Note also that the fidelity image is the ratio of (convolved model image) and (absolute value of the difference image truncated at 0.7 x rms of difference image). Importantly, in the figures below this latter rms value is different for each of the K and C array cases, resulting in the C array Fidelity image showing more structure despite (or as a consequence of) having half the rms value for its difference image.
