... Cameras NIC1, and NIC2, each contain 3 polarizers, whose principal axes of transmission are separated by 120 degrees. ... As with the imaging filters, sensitivity information for the two sets of polarizers may be obtained from the Exposure Time Calculator. It gives the same information as was described in Chapter 4: namely a sensitivity curve, plotted as flux against time for a constant S/N ratio and an exposure exclusion curve for both point and extended sources. ...
