Electronic crosstalk produces a signal in one or more amplifier quadrants in response to a stimulus in another quadrant. In the WFC3 IR camera, the crosstalk arises during the readout and appears as a negative mirror image of the source. Positioned symmetrically opposite the source about the dividing line between each of the coupled readout amplifier quadrants, the crosstalk appears at a lower level than the surrounding background, at the level of ~1e-06 that of the source signal. The level is low enough that it should not be an issue for most programs; dithering can help mitigate the effect. This ISR characterizes the position, intensity and shape of the crosstalk effect as seen during TV3 ground testing.
