Inter-pixel capacitance : prospects for deconvolution

  title={Inter-pixel capacitance : prospects for deconvolution},
  author={P. McCullough August},
We provide an IDL implementation of Fourier deconvolution and apply it to data from a WFC3 H1RG near-infrared array detector that exhibits inter-pixel capacitance (IPC). The deconvolution removes the most obvious deleterious effect of IPC: the cross-like pattern (i.e. the arithematic symbol for addition, “+”) of charge around pixels with large dark current, a.k.a. “hot” pixels. We also exhibit a case in which our physical interpretation of a detector defect changed qualitatively before and… CONTINUE READING
