Basic usage: load visibilities from a Measurement Set, run Spotless imager.

from spotless import SpotlessImager, load_measurements import numpy as np # Load visibilities from a Measurement Set ms_path = 'path/to/measurement_set.ms' u, v, freq, vis, weights = load_measurements(ms_path) # Create imager and run deconvolution imager = SpotlessImager() sky = imager.run(u, v, freq, vis, weights, npix=512, cellsize=0.1) print('Reconstructed sky shape:', sky.shape)

Debug

Known issues

gotchaPython version: Ensure Python 3.6+ is used. Spotless may not work with Python 2 or older versions.

fix

Use Python 3.6 or higher.

affects: 0.4.1

gotchaMeasurement Set requires casa-formatted data. If loading from other formats, conversion to MS is necessary.

fix

Use casacore or other tools to convert to MeasurementSet.

affects: 0.4.1

gotchaNumpy version compatibility: Older numpy versions may cause issues. Use numpy >= 1.16.

fix

Upgrade numpy via pip install --upgrade numpy

affects: 0.4.1
