From f1e3cc2d77b80bef083360da2a14827b8514e2cb Mon Sep 17 00:00:00 2001 From: lmachadopolettivalle <27741646+lmachadopolettivalle@users.noreply.github.com> Date: Mon, 20 Nov 2023 11:21:12 +0100 Subject: [PATCH] Telescope Class: Accept OSKAR and RASCIL backends (#522) * Introduce enum for backend, which currently will contain OSKAR and RASCIL * Allow Telescope class to hold OSKAR and RASCIL specific telescopes * Modify telescope tests to use new functionality for reading telescope data * Do not run github actions if in a draft PR * Finalize RASCIL functionality in Telescope * Add tests for RASCIL telescopes * Improve tests for RASCIL telescopes * Use Telescope constructor in all scripts, and correctly format version into Telescope if needed * Update notebooks --- .github/workflows/test.yml | 1 + .../_example_scripts/example_interfe_simu.py | 2 +- .../_example_scripts/example_tel_set.py | 2 +- karabo/examples/source_detection.ipynb | 2 +- .../examples/source_detection_big_files.ipynb | 2 +- karabo/performance_test/time_karabo.py | 2 +- .../time_karabo_parallelization_by_channel.py | 2 +- .../performance_test/time_karabo_slurm_h5.py | 2 +- karabo/simulation/line_emission.py | 2 +- karabo/simulation/telescope.py | 258 ++++++++++++++---- karabo/simulator_backend.py | 6 + karabo/test/test_beam.py | 6 +- karabo/test/test_beam_ska-low.py | 2 +- karabo/test/test_image.py | 2 +- karabo/test/test_ionosphere.py | 2 +- karabo/test/test_long_observation.py | 4 +- karabo/test/test_mock_mightee.py | 2 +- karabo/test/test_simulation.py | 11 +- karabo/test/test_skymodel.py | 38 +-- karabo/test/test_source_detection.py | 4 +- karabo/test/test_spectral_line.py | 4 +- karabo/test/test_system_noise.py | 2 +- karabo/test/test_telescope.py | 124 ++++++++- karabo/test/test_telescope_baselines.py | 2 +- 24 files changed, 367 insertions(+), 117 deletions(-) create mode 100644 karabo/simulator_backend.py diff --git a/.github/workflows/test.yml b/.github/workflows/test.yml index 03d9ad3c..811e2ada 100644 --- a/.github/workflows/test.yml +++ b/.github/workflows/test.yml @@ -12,6 +12,7 @@ on: jobs: Test_Karabo: + if: github.event.pull_request.draft == false runs-on: ubuntu-latest steps: -
