Match Spectral

MATCH_SPECTRAL

See the source code.

This test verifies that region spectral profiles are consistent across spatially and spectrally matched images in different formats (FITS and CASA).

1. Frontend sends: OPEN_FILE (OpenFile) for four files

   File 1 (FITS CO 2-1):

   directory = "set_QA"
   file = "HD163296_CO_2_1.fits"
   file_id = 100
   render_mode = RASTER
   

   File 2 (FITS 13CO):

   directory = "set_QA"
   file = "HD163296_13CO_2-1.fits"
   file_id = 101
   render_mode = RASTER
   

   File 3 (FITS C18O):

   directory = "set_QA"
   file = "HD163296_C18O_2-1.fits"
   file_id = 102
   render_mode = RASTER
   

   File 4 (CASA CO 2-1):

   directory = "set_QA"
   file = "HD163296_CO_2_1.image"
   file_id = 103
   render_mode = RASTER
   

2. Backend returns: OPEN_FILE_ACK for each file

3. Frontend sends: SET_REGION (SetRegion) on file 100

   file_id = 100
   region_id = 1
   region_type = RECTANGLE
   control_points = [{x: 200, y: 200}, {x: 200, y: 200}]
   rotation = 0
   

4. Frontend sends: SET_SPECTRAL_REQUIREMENTS (SetSpectralRequirements) for each file

   file_id = <100-103>
   region_id = 1
   spectral_profiles = [{coordinate: "z", stats_types: [Mean]}]
   

5. Backend returns: SPECTRAL_PROFILE_DATA (SpectralProfileData) for each file

Check 1: the SPECTRAL_PROFILE_DATA should satisfy:

• All region_id values equal 1

• The spectral profile for file 100 (FITS) is identical to the profile for file 103 (CASA) — same data in different formats should produce the same results

After rotating the region to 30 degrees:

6. Frontend sends: SET_REGION (SetRegion) with updated rotation

   file_id = 100
   region_id = 1
   region_type = RECTANGLE
   control_points = [{x: 200, y: 200}, {x: 200, y: 200}]
   rotation = 30
   

7. Backend returns: SPECTRAL_PROFILE_DATA for each file (progress = 1)

Check 2: the SPECTRAL_PROFILE_DATA should satisfy:

• All region_id values match the requirements

• The rawValuesFp64 arrays for file 100 (FITS) and file 103 (CASA) are element-by-element identical
