This detailed understanding of the ACS / WFC
readout dark should improve algorithms for badpixel masking and for pixelbased correction of CTE / CTI (charge transfer inefficiency), which is also most significant for pixels furthest from the amplifiers.
In recent ACS / WFC fullchip images,
readout dark contributes about 0.5 electrons of noise to pixels furthest from the readout amplifiers.
We call this contribution «
readout dark».
Readout dark increases across the detector; pixels furthest from the amplifiers (last to be read out) are subject to the most
readout dark.
That is, we measure read noise to be ~ 4.0 electrons closest to the amplifiers and ~ 4.5 electrons (including
readout dark) furthest from them (varying somewhat for each amplifier) in recent images.
Not exact matches
The light and
dark sections of the
readout display are controlled by the amount of current flowing into them.
Only a large digital speed
readout is evident, as the myriad of warning lights remain
dark until trouble arises.
In addition to that, the GT - 86 also has aluminum pedals, a navigation system, gauges that light with red neon, digital
readouts, and a gray instrument panel that seamlessly molds into the
darker dash.
