Region Spectral Profile

See the source code: FITS | CASA | HDF5

Measures the time to compute a mean spectral profile over a large rectangular region on a 1000-channel cube. The elapsed time is measured between the SET_SPECTRAL_REQUIREMENTS request and the SPECTRAL_PROFILE_DATA response with progress = 1.

  1. Frontend sends: OPEN_FILE (OpenFile)

    directory = "set_QA_performance"
file = "cube_B_03200_z01000.<fits|image|hdf5>"
file_id = 0

  2. Frontend loads tiles and sets cursor at (1, 1)

  3. Frontend sends: SET_REGION (SetRegion)

    region_type = RECTANGLE
control_points = [{x: 800, y: 800}, {x: 400, y: 400}]
rotation = 0

  4. Frontend sends: SET_SPECTRAL_REQUIREMENTS (SetSpectralRequirements)

    file_id = 0
region_id = 1
spectral_profiles = [{coordinate: "z", stats_types: [Mean]}]

  5. Backend streams: SPECTRAL_PROFILE_DATA with increasing progress

Check 1: within 120,000 ms:

  • SET_REGION_ACK.success = True

  • SPECTRAL_PROFILE_DATA reaches progress = 1
