$\ast$ Units of 10^-18 W m^-2. The 1 $\sigma$ flux measurement uncertainty is 2.6 $\times$ 10^-18 W m^-2 and 5.2 $\times$ 10^-18 W m^-2 beyond 2.4 $\mu$ m. This (standard deviation) value was derived from a large sample of flux measurements within apertures placed on sky regions and at various wavelengths.
$\ast\ast$ Units of 10^-18 W m^-2. The 1 $\sigma$ flux measurement uncertainty is 3.3 $\times$ 10^-18 W m^-2 and 6.6 $\times$ 10^-18 W m^-2 beyond 2.4 $\mu$ m.
$\dagger$ Units of 10^-18 W m^-2 arcsec^-2. The 1 $\sigma$ noise level is 1.0 $\times$ 10^-18 W m^-2 arcsec^-2.
