empyrean.WeightingLayer¶

class WeightingLayer(kind=WeightingLayerKind.OBSERVATORY_RULE, obs_code='', sigma=(1.0, 1.0), start_epoch_mjd_tdb=None, end_epoch_mjd_tdb=None, scale=1.0, max_gap_days=0.5)[source]

Bases: object

One element of the weighting pipeline. Tagged-union shape — the active fields depend on kind.

Mirrors scott::weighting::WeightingLayer.

Methods

__init__([kind, obs_code, sigma, ...])

Attributes

`end_epoch_mjd_tdb`	End of applicable time range (MJD TDB).
`kind`
`max_gap_days`	Max gap (days) between observations to count as the same night (NightlyDeweighting only).
`obs_code`	MPC observatory code (e.g. `"F51"`).
`scale`	Scale factor on the final weight.
`sigma`	1σ (RA·cos(δ), Dec) in arcseconds.
`start_epoch_mjd_tdb`	Start of applicable time range (MJD TDB).

Parameters:

kind (WeightingLayerKind)
obs_code (str)
sigma (tuple[float, float])
start_epoch_mjd_tdb (float | None)
end_epoch_mjd_tdb (float | None)
scale (float)
max_gap_days (float)

kind: WeightingLayerKind = 'observatory_rule'

obs_code: str = '': MPC observatory code (e.g. "F51").

sigma: tuple[float, float] = (1.0, 1.0): 1σ (RA·cos(δ), Dec) in arcseconds.

start_epoch_mjd_tdb: float | None = None: Start of applicable time range (MJD TDB). None = unbounded.

end_epoch_mjd_tdb: float | None = None: End of applicable time range (MJD TDB). None = unbounded.

scale: float = 1.0: Scale factor on the final weight.

max_gap_days: float = 0.5: Max gap (days) between observations to count as the same night (NightlyDeweighting only).
