File slots.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.

SlotDefinition - #include <slots.h>
Base class for helper classes that define slots on SourceTable/SourceRecord.
Each type of slot corresponds to a subclass of SlotDefinition, and each actual slot corresponds to a particular field name prefix. For instance, to look up the centroid slot, we look for fields named “slot_Centroid_x” and “slot_Centroid_y”. Instead of actually naming a particular field that, however, we use Schema’s alias mechanism (see AliasMap) to make these field name lookups resolve to the name of other fields. The actual definition of the slots is thus managed by the Schema’s AliasMap, though a SourceTable object will cache Keys for the various slots to make sure accessing slot values is efficient (more precisely, when you set an alias related to a slot on an AliasMap, any table it corresponds to will receive a notification that it should update its Keys). These cached Keys are actually stored within the SlotDefinition (as data members of derived classes).
Note that the uncertainty and failure flag components of slots are not required; a slot may have only a measurement defined, or a measurement and either one of these (but not both). A slot may not have only an uncertainty and/or a a failure flag, however.
A SlotDefinition instance is not just an internal object used by SourceTable; it can also be used to inspect the slots via SourceTable::getXxxSlot(), which is now the preferred way to access the Keys that slots correspond to. SlotDefinition objects should only be constructed by SourceTable, however.

Public Functions
-
SlotDefinition(std::string const &name) Construct a SlotDefinition from the name of the slot (e.g. “Centroid” or “PsfFlux”)
-
std::string
getName() const Return the name of the slot (e.g. “Centroid” or “PsfFlux”)
-
std::string
getAlias() const Return the alias field prefix used to lookup Keys for the slot.
This simply prepends “slot_” to the slot name.

SlotSuite¶ - #include <slots.h>
An aggregate containing all of the current slots used in SourceTable.
This is essentially for internal use by SourceTable only; it is defined here to keep the source code for the slot mechanism in one place as much as possible.
