MATCH_SPATIAL

See the source code.

This test verifies cursor value and spatial profile consistency with spatially matched images across 4 related image files.

  1. Frontend sends: OPEN_FILE (OpenFile) for 4 images

    file = "HD163296_CO_2_1.fits", file_id = 100
file = "HD163296_13CO_2-1.fits", file_id = 101
file = "HD163296_C18O_2-1.fits", file_id = 102
file = "HD163296_CO_2_1.image", file_id = 103

  2. Frontend sends: SET_CURSOR (SetCursor) at (200.0, 200.0)

  3. Frontend sends: SET_SPATIAL_REQUIREMENTS (SetSpatialRequirements) for x and y coordinates

  4. Backend returns: SPATIAL_PROFILE_DATA (SpatialProfileData) for all images

Check 1: the spatial profile data should satisfy:

  • Cursor value for fileId 100 = -0.0023265306372195482

  • Spatial profile data matches across all 4 images with 4 decimal precision

  • x coordinate raw profile values at indices [0, 500, 1000, 1500] = [36, 242, 86, 48]

  • y coordinate raw profile values at indices [0, 500, 1000, 1500] = [84, 163, 231, 66]

  • Profiles array has end = 432 for both x and y
