CLEAN results for xBSDC_4-70B7 simulations

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.
