GaussianMeasurementError

class discO.GaussianMeasurementError(*, c_err: Callable | CoordinateFrame | SkyCoord | BaseRepresentation | float | ndarray | Mapping | Quantity | None = None, method: str | None = None, **kwargs)

Bases: RVS_Continuous

Draw a realization given Gaussian measurement errors.

Parameters:

rvscallable() (optional, keyword-only)

c_errfloat or callable() or None (optional, keyword-only)

Callable with single mandatory positional argument – coordinates (“c”) – that returns the absolute error.

frame: frame-like or None (optional, keyword-only)

The frame of the observational errors, ie the frame in which

the error function should be applied along each dimension.

representation_type: |Representation| or None (optional, keyword-only)

The coordinate representation in which to resample along each dimension.

**params

Stored as params.

Raises:

ValueError

If “norm” not in the name in rvs.
