w4snr	wise_prelimsc	WISE	W4 profile-fit measurement signal-to-noise ratio This value is the ratio of the flux (w4flux) to flux uncertainty (w4sigflux)in the W4 profile-fit photometry measurement. This column is default if w4flux is negative, or if w4flux or w4sigflux are default.	real	4		-0.9999995e9
