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.

baseline

type:

string

doc:

Perform baseline selection using a filter-substep. Refer to Filter for additional information.

default:

""

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.
