示例1: test_reproject_cube
# 需要导入模块: from astropy.units import Quantity [as 别名]
# 或者: from astropy.units.Quantity import sum [as 别名]
def test_reproject_cube():
# TODO: a better test can probably be implemented here to avoid
# repeating code
filenames = FermiGalacticCenter.filenames()
spectral_cube = SpectralCube.read(filenames['diffuse_model'])
exposure_cube = SpectralCube.read(filenames['exposure_cube'])
original_cube = Quantity(np.nan_to_num(spectral_cube.data.value),
spectral_cube.data.unit)
spectral_cube = spectral_cube.reproject_to(exposure_cube)
reprojected_cube = Quantity(np.nan_to_num(spectral_cube.data.value),
spectral_cube.data.unit)
# 0.5 degrees per pixel in diffuse model
# 2 degrees in reprojection reference
# sum of reprojected should be 1/16 of sum of original if flux-preserving
expected = 0.0625 * original_cube.sum()
actual = reprojected_cube.sum()
assert_quantity_allclose(actual, expected, rtol=1e-2)
