Detailed Description

Information about a CCD or other imaging detector

Supports conversion of CameraPoint between FOCAL_PLANE and pixel-based coordinate systems. Also an iterator over amplifiers (in C++ use begin(), end(), in Python use "for amplifier in detector").

Todo:: : this would probably be a bit more robust if it used a ConstAmpInfoCatalog (a catalog with const records) but I don't think const catalogs really work yet; for instance it is not possible to construct one from a non-const catalog, so I don't know how to construct one.

Note: : code definitions use lsst::afw::table:: instead of table:: because the latter confused swig when I tried it. This is a known issue: ticket #2461.

Make a Detector

Warning

The keys for the detector-specific coordinate systems in the transform registry must include the detector name (even though this is redundant).

Exceptions

lsst::pex::exceptions::InvalidParameterError

if:

any amplifier names are not unique
any CamerSys in transformMap has a detector name other than "" or this detector's name

Parameters

name	name of detector's location in the camera
id	detector integer ID; used as keys in some tables
type	type of detector
serial	serial "number" that identifies the physical detector
bbox	bounding box
ampInfoCatalog	catalog of amplifier information
orientation	detector position and orientation in focal plane
pixelSize	pixel size (mm)
transforms	map of CameraSys: lsst::afw::geom::XYTransform, where each transform's "forwardTransform" method transforms from PIXELS to the specified camera system
