AssociationConfig#
- class lsst.ap.association.AssociationConfig(*args, **kw)#
Bases:
ConfigConfig class for AssociationTask.
Attributes Summary
Per-axis position uncertainty (arcsec) substituted for raErr/decErr values that are missing, non-finite, or non-positive when computing chi^2.
Maximum distance in arcseconds for a DIASource to be matched to a DIAObject.
Floor on the per-axis position uncertainty (arcsec) used when computing chi^2.
Attributes Documentation
- fallbackSigmaArcSeconds#
Per-axis position uncertainty (arcsec) substituted for raErr/decErr values that are missing, non-finite, or non-positive when computing chi^2. Should reflect a plausible size for an unmeasured per-axis uncertainty (e.g., one LSSTCam pixel ~= 0.2 arcsec). Has no effect on rows that carry valid uncertainty values. (
float, default0.2)
- maxDistArcSeconds#
Maximum distance in arcseconds for a DIASource to be matched to a DIAObject. This is the sole association radius: every DIAObject within this distance is a match candidate, ranked by position chi^2 when uncertainties are available and by angular distance otherwise. (
float, default1.0)
- sigmaFloorArcSeconds#
Floor on the per-axis position uncertainty (arcsec) used when computing chi^2. (
float, default0.05)
