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.

Functions

std::shared_ptr<afw::image::TransmissionCurve const> makeCoaddTransmissionCurve(std::shared_ptr<afw::geom::SkyWcs const> coaddWcs, afw::table::ExposureCatalog const &inputSensors)

Create a TransmissionCurve that represents the effective throughput on a coadd.

Return

a new TransmissionCurve object.

Parameters

  • [in] coaddWcs: WCS that relates the coadd coordinate system to the sky.

  • [in] inputSensors: A catalog containing the WCSs, bounding boxes and polygons, coaddition weights (in a field called ‘weight’), and TransmissionCurves of the sensor-level images that went into the coadd.

Exceptions

  • NotFoundError: Thrown if the ‘weight’ field does not exist in the schema.

  • InvalidParameterError: Thrown if one or more inputs do not have a TransmissionCurve or a Wcs (ValidPolygons may be null to indicate no spatial restrictions other than the bounding box).
