A polarized source

A polarized source

The WSRT records polarization in X and Y and produces four correlation products: XX XY YX YY.

For the simulations with unpolarized sources we've been assigning the source brightness solely to I and leave Q, U and V equal to zero.

The correlation products reflect this by having half the flux in XX, the other half in YY and nothing in the cross products.

For this first example we use a linearly polarized wave (i.e. V = 0), which is completely vertically polarized (i.e. psi = 0, Q = a positive value, U = 0).

The attached LSM in the data products below is the same as SSSC1 but with the Q value edited to be 10.0 Jy.
