DipoleAnalysis

class lsst.ip.diffim.DipoleAnalysis

Bases: object

Functor class that provides (S/N, position, orientation) of measured dipoles

Methods Summary

__call__(source) Parse information returned from dipole measurement
displayDipoles(exposure, sources) Display debugging information on the detected dipoles
getCentroid(source) Get the centroid of the dipole; average of positive and negative lobe
getOrientation(source) Calculate the orientation of dipole; vector from negative to positive lobe
getSn(source) Get the total signal-to-noise of the dipole; total S/N is from positive and negative lobe
