Definition of SOT polarization coordinate

This definition is the same as that used in the analysis of the suntest data of 2004.8 and consistent with the ASP definition, ie. positive V at blue side of spectral line gives positive magnetic flux. This is also consistent with the definition of Stokes V: (right circ. – left circ.), where right circular polarization is positive when electric vector rotates clockwise looking at the source.

This definition is applied to the Stokes vectors obtained after application of the X-matrix. Raw Stokes products of FPP are not consistent with this definition.
