Moments

See the source code: FITS | CASA | HDF5

Measures the time to generate all 13 moment images from a spectral cube. The elapsed time is measured between the MOMENT_REQUEST request and the MOMENT_RESPONSE response.

  1. Frontend sends: OPEN_FILE (OpenFile)

    directory = "set_QA_performance"
file = "S255_IR_sci.spw25.cube.I.pbcor.<fits|image|hdf5>"
file_id = 0

  2. Frontend loads tiles, sets cursor at (960, 960), and requests spectral profile

  3. Frontend sends: MOMENT_REQUEST (MomentRequest) for all 13 moments

    file_id = 0
moments = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
axis = SPECTRAL
mask = Include
pixel_range = {min: 0.1, max: 1.0}
spectral_range = {min: 0, max: 400}
rest_freq = 335500000000

    The 13 moment types: Average, Integrated, Weighted Coordinate, Weighted Dispersion Coordinate, Median, Median Coordinate, Standard Deviation, RMS, Abs Mean Deviation, Maximum, Maximum Coordinate, Minimum, Minimum Coordinate.

  4. Backend returns: MOMENT_RESPONSE with 13 openFileAcks

Check 1: within the momentTimeout (400,000 ms):

  • MOMENT_RESPONSE.success = True

  • MOMENT_RESPONSE.openFileAcks.length = 13

  • All openFileAcks[].success = True
