Variable Documentation

CameraSysPrefix const lsst::afw::cameraGeom::ACTUAL_PIXELS = CameraSysPrefix("ActualPixels")

The actual pixels where the photon lands and electrons are generated (unbinned) This takes into account manufacturing defects, "tree ring" distortions and other such effects.

This is a detector prefix; call Detector.makeCameraSys(ACTUAL_PIXELS) to make a full coordsys.

Definition at line 37 of file CameraSys.cc.

CameraSys const lsst::afw::cameraGeom::FOCAL_PLANE = CameraSys("FocalPlane")

Focal plane coordinates: Rectilinear x, y (and z when talking about the location of a detector) on the camera focal plane (mm). For z=0 choose a convenient point near the focus at x, y = 0.

Definition at line 29 of file CameraSys.cc.

CameraSysPrefix const lsst::afw::cameraGeom::PIXELS = CameraSysPrefix("Pixels")

Nominal pixels on the detector (unbinned) This ignores manufacturing imperfections, "tree ring" distortions and all other such effects. It is a uniform grid of rectangular (usually square) pixels.

This is a detector prefix; call Detector.makeCameraSys(PIXELS) to make a full coordsys.

Definition at line 33 of file CameraSys.cc.

CameraSys const lsst::afw::cameraGeom::PUPIL = CameraSys("Pupil")

Pupil coordinates: Angular x,y offset from the vertex at the pupil (radians).

Definition at line 31 of file CameraSys.cc.

CameraSysPrefix const lsst::afw::cameraGeom::TAN_PIXELS = CameraSysPrefix("TanPixels")

Tangent-plane pixels on the detector (unbinned)

Converting from PIXELS to TAN_PIXELS has the effect of removing optical distortion (and the distortion due to rectangular pixels) with the point at the center of the detector being unaffected by the transformation.

In detail, PIXELS->TAN_PIXELS is PIXELS->PUPIL plus an affine transformation, such that:

• The x,y axes are parallel to the detector axes
• The dimensions are nominal pixels at the center of the focal plane (where nominal pixels size is mean of x, y pixel size).
• The point at the center of the detector has the same value in PIXELS and TAN_PIXELS

This is a detector prefix; call Detector.makeCameraSys(TAN_PIXELS) to make a full coordsys.
