Clipper

Simulates visibilities from a given skymodel and uses the result to clip bright sources from the data. Because this steps performs prediction, options of the Predict step are also valid.

inputs

type

type:: string
default:: clipper
doc:: Case-insensitive step type; must be ‘clipper’.

amplmax

type:: float
default:: 50.0 for LBA, 5.0 for HBA
doc:: Sets the clip level for the data.

flagallcorrelations

type:: boolean
default:: True
doc:: Flag all correlations for a baseline if a single correlation exceeds amplmax.

freqstep

type:: int
doc:: Perform the visibility prediction only once every frequency_step channels. The next frequency_step - 1 channels will use these visibilities until the next prediction.

step_name

type:: string
default:: clipper
doc:: unique name for the step.

timestep

type:: int
default:: 5
doc:: Perform the visibility prediction only once every time_step steps. The next time_step - 1 will use these visibilities until the next prediction.
