Basic detector characteristics.

		SPIFFIER slow	NIX slow	NIX fast
Min. exp.^(a)	e⁻	1.6	1.97	0.034
Gain	e⁻/ADU	2.0	5.2	2.6
Full well	ke⁻	80	85	85
Read noise^(b)	e⁻	12/7	17/9	50

Notes. ^(a)Minimum exposure time is given for the full frame. ^(b)Read noise for the slow mode corresponds to exposures of 2 s (correlated double sampling) and 60 s (up-the-ramp sampling); with the fast mode it is for single uncorrelated reads.
