UVWFlagger

Flag based on UVW coordinates, possibly in the direction of another source.

inputs

type

type:

string

default:

uvwflagger

doc:

Case-insensitive step type; must be ‘uvwflagger’ or ‘uvwflag’ .

beammode

type:

enum

doc:

Beam mode to apply, can be “array_factor”, “element” or “default”. Default is to apply both the element beam and the array factor .

symbols:

array_factor, element, default

count.path

type:

string?

default:

""

doc:

The directory where to create the flag percentages table. If empty, the path of the input MS is used .

count.save

type:

boolean

default:

False

doc:

The directory where to create the flag percentages table. If empty, the path of the input MS is used .

phasecenter

type:

string?

doc:

If given, use this phase center to calculate the UVW coordinates to flag on. The vector can consist of 1, 2 or, 3 values. If one value is given, it must be the name of a moving source (e.g. SUN or JUPITER). Otherwise the first two values must contain a source position that can be given in sexagesimal format or as a value followed by a unit. The third value can contain the direction type; it defaults to J2000. Possible types are GALACTIC, ECLIPTIC, SUPERGAL, J2000, B1950 (as defined in the casacore Measures system) .
