... The analysis of NICMOS polarization images is aimed at determining the Stokes' Parameters, and from those the polarization angle and degree for each pixel. NICMOS Camera 1 and Camera 2 each contain three polarizers, whose principal axes of transmission are separated by 120 degrees. ... The images in the three filters need to be compared, in order to produce the Stokes' parameters. ... The Stokes parameters can then be combined to yield the polarized intensity, I p: . ...

... I see the same problem all the time in undergraduate assignments: someone comes up with an answer that is clearly, wildly, hopelessly wrong (e.g. the mass of some star is 0.7 kg, or an asteroid is travelling at 1010 m s-1 (faster than light), or the Earth took 1011 years to form (much longer than the age of the universe). ... This means that every valid equation should work equally well, regardless of the units you use (as long as they are self consistent). ... Do you think this could be correct? ...
