Bases: object

FluxMeasurement is a logical representation of a flux measurement.

spw_id

ID of spectral window associated with flux measurement.

I

Stokes I flux density as FluxDensity object.

Q

Stokes Q flux density as FluxDensity object.

U

Stokes U flux density as FluxDensity object.

V

Stokes V flux density as FluxDensity object.

spix

Spectral index of the flux measurement.

uvmin

Scale (in klambda) of the measured (large scale) extent of the flux source (if greater than zero).

uvmax

Scale (in klambda) where (small scale) structure has been measured within the flux source, or a limit on the resolved structure.

origin

Origin of the flux measurement.

age

Age of the flux measurement.

queried_at

Date-timestamp when flux measurement was queried (e.g. from catalog service).
