BeamInfo¶
- class lsst.cbp.BeamInfo(cameraGeom, name, holePos, isOnPupil, isOnFocalPlane, focalPlanePos, pupilPos, focalFieldAngle, pupilFieldAngle)¶
Bases:
object
Information 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
isVisible
is False.- Parameters:
- cameraGeom
lsst.afw.cameraGeom.Camera
Camera geometry
- name
str
Beam name
- holePospair of
float
Hole position on CBP mask (x, y mm)
- isOnPupil
bool

- isOnFocalPlane

Notes
Attributes
- name
str
Name of beam.
- holePospair 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
The name of the detector that the beam falls on, or None if isOnDetector is False.
The position of the spot on the detector, or (nan, nan) if
isOnDetector
is False.Is the spot from the beam on a detector?
Is light from the beam visible on a detector?
