File Orientation.h¶
-
namespace
lsst Class for a simple mapping implementing a generic AstrometryTransform.
Remove all non-astronomical counts from the Chunk Exposure’s pixels.
Forward declarations for lsst::utils::Cache
For details on the Cache class, see the Cache.h file.
It uses a template rather than a pointer so that the derived classes can use the specifics of the transform. The class simplePolyMapping overloads a few routines.
A base class for image defects
Numeric constants used by the Integrate.h integrator routines.
Compute Image Statistics
- Note
Gauss-Kronrod-Patterson quadrature coefficients for use in quadpack routine qng. These coefficients were calculated with 101 decimal digit arithmetic by L. W. Fullerton, Bell Labs, Nov 1981.
- Note
The Statistics class itself can only handle lsst::afw::image::MaskedImage() types. The philosophy has been to handle other types by making them look like lsst::afw::image::MaskedImage() and reusing that code. Users should have no need to instantiate a Statistics object directly, but should use the overloaded makeStatistics() factory functions.

Orientation - #include <Orientation.h>
Describe a detector’s orientation in the focal plane
All rotations are about the reference point on the detector. Rotations are intrinsic, meaning each rotation is applied in the coordinates system produced by the previous rotation. Rotations are applied in this order: yaw (Z), pitch (Y’), and roll (X’’).
- Warning
: default refPoint is -0.5, -0.5 (the lower left corner of a detector). This means that the default-constructed Orientation is not a unity transform, but instead includes a 1/2 pixel shift.

fpPosition: Focal plane position of detector reference point (mm)refPoint: Reference point on detector (pixels). Offset is measured to this point and all all rotations are about this point. The default value (-0.5, -0.5) is the lower left corner of the detector.yaw: yaw: rotation about Z (X to Y), 1st rotationpitch: pitch: rotation about Y’ (Z’=Z to X’), 2nd rotationroll: roll: rotation about X’’ (Y’’=Y’ to Z’’), 3rd rotation
