makePixelToTanPixel¶
- lsst.afw.cameraGeom.makePixelToTanPixel(bbox, orientation, focalPlaneToField, pixelSizeMm)¶
Make a Transform whose forward direction converts PIXELS to TAN_PIXELS for one detector.
- Parameters:
- bbox
lsst.geom.Box2I
Detector bounding box.
- orientation
lsst.afw.cameraGeom.Orientation
Orientation of detector in focal plane.
- focalPlaneToField
lsst.afw.geom.TransformPoint2ToPoint2
A transform that converts from focal plane (mm) to field angle coordinates (radians) in the forward direction.
- pixelSizeMm
lsst.geom.Extent2D
Size of the pixel in mm in X and Y.
- bbox
- Returns:
- transform
lsst.afw.geom.TransformPoint2ToPoint2
A transform whose forward direction converts PIXELS to TAN_PIXELS.
- transform
Notes
PIXELS and TAN_PIXELS are described in the CameraGeom documentation under camera coordinate systems.
