create_image

create_image(npixel=512, cellsize=1.5e-05, polarisation_frame=<data_models.polarisation.PolarisationFrame object>, frequency=array([1.e+08]), channel_bandwidth=array([1000000.]), phasecentre=None, nchan=None) → data_models.memory_data_models.Image

Create an empty template image consistent with the inputs.

Parameters

• npixel – Number of pixels

• polarisation_frame – Polarisation frame (default PolarisationFrame(“stokesI”))

• cellsize – cellsize in radians

• frequency –

• channel_bandwidth – Channel width (Hz)

• phasecentre – phasecentre (SkyCoord)

Returns
