BeamInfo¶

class
lsst.cbp.BeamInfo(cameraGeom, name, holePos, isOnPupil, isOnFocalPlane, focalPlanePos, pupilPos, focalFieldAngle, pupilFieldAngle)¶ Bases:
objectInformation about a beam at the telescope.
Note that this is information about the fiducial position of the beam; it tell you nothing about the rest of the beam. Thus, for instance, a broad beam may easily have some light on a detector even if
isVisibleis False.Parameters: - cameraGeom :
lsst.afw.cameraGeom.Camera Camera geometry
- name :
str Beam name
- holePos : pair of
float Hole position on CBP mask (x, y mm)
- isOnPupil :
bool See fields below
- isOnFocalPlane :
bool See fields below
- focalPlanePos : pair of
float See fields below
- pupilPos : pair of
float See fields below
- focalFieldAngle : pair of
float See fields below
- pupilFieldAngle : pair of
float See fields below
Notes
Attributes
- name :
str - Name of beam.
- holePos : pair of
float - Position of hole on CBP mask (x, y mm).
- isOnPupil :
bool - True if the beam is likely on the pupil and not obscured by the secondary.
- isOnFocalPlane :
bool True if the beam is likely on the focal plane.
This is independent of
isOnPupil; both must be true for light from the beam to be on the focal plane.- focalPlanePos :
lsst.geom.Point2D - Telescope focal plane position of beam (x, y mm).
- focalFieldAngle :
lsst.geom.Point2D - Focal plane field angle of beam (x, y rad).
- pupilFieldAngle :
lsst.geom.Point2D - Pupil field angle of beam (x, y rad).
- pupilPos :
lsst.geom.Point2D - Telescope pupil plane position of beam (x, y mm).
Attributes Summary
detectorNameThe name of the detector that the beam falls on, or None if isOnDetector is False. detectorPosThe position of the spot on the detector, or (nan, nan) if isOnDetectoris False.isOnDetectorIs the spot from the beam on a detector? isVisibleIs light from the beam visible on a detector?
