primary_beam

Tests for the functions in wodenpy/primary_beam, which are wrappers around C++ to run the EveryBeam primary beam code.

test_check_ms_telescope_type_matches_element_response.py

This function checks that the telescope type in a measurement set allows for the requested element response. For example, the only type of primary beam model that can be used with the MWA telescope is the MWA beam model. Checks by reading in three measurement sets with MWA, LOFAR, and OSKAR telescope types. Asserts function fails if an incorrect element response is requested, and passes if an appropriate element response is requested. Also writes out an unknown telescope type measurement set to check that fails as well.

test_run_everybeam_over_threads.py

Checks that the multi-threaded version of calling EveryBeam gives the same answer as the serial version when running the LOFAR LBA beam. Don’t check actual values here as that’s done in cmake_testing/GPU_or_C_code/call_everybeam/

test_run_everybeam_over_threads_MWA.py

Same as test_run_everybeam_over_threads.py, but using the MWA primary beam, which requires passing in parallactic angles as EveryBeam doesn’t rotate the MWA primary beam for some reason.
