6. Write new C/GPU code to calculate Q/U from Stokes I and RM/pol frac/intrinsic pol angle #61

Closed JLBLine closed 1 month ago

JLBLine commented 1 month ago

Need a new function, source_components::kern_extra_RM_stokesQU, that takes in the Stokes I that should have already been extrapolated, the RM, the linear polarisation fraction, and the intrinsic polarisation angle, and calculates Stokes Q and U.

Testing - will have to edit cmake_testing/GPU_code/source_components/test_extrap_stokes.c to include Stokes Q/U. Likely many other tests in that directory should be updated to include different polarisation examples (e.g test_kern_calc_visi_common.c, test_source_component_common.c).
