Reset rate (period)	0.074 Hz (13.464 s)
Operation	$256\times2$ pix
Operated row	$117^{\rm th}$ , $125^{\rm th}$
Binning	$4\times1$ pix
Virtual pixel scale	$9\hbox{$.\!\!^{\prime\prime}$ }36\times9\hbox{$.\!\!^{\prime\prime}$ }36$	$10\hbox{$.\!\!^{\prime\prime}$ }4\times9\hbox{$.\!\!^{\prime\prime}$ }36$

Notes. ^(*) Effective exposures for point sources are determined not by the sampling rate, but by the dwelling time of a source on a pixel.
$^{(\dagger)}$ Estimated value from readout noise in shuttered configuration in-orbit.
$^{(\ddagger)}$ Defined as where the responsivity for a given energy is larger than 1/e of the peak.
