Modeling of the degradation of the Titan polarization Q due to the cancelation of opposite polarization components + Q and −Q caused by the limited resolution; a) unlimited resolution; b) HST PSF at 630 nm (F625W); c) HST PSF at 1 μm (NIC1); and d) HST PSF at 2 μm (NIC2). The gray scale spans for all panels the range from −2% (black) to + 2% (white) of the peak intensity of the initial perfect intensity image.
