CameraWrapper

class lsst.afw.cameraGeom.testUtils.CameraWrapper(plateScale=20.0, radialDistortion=0.925, isLsstLike=False)

Bases: object

A simple Camera and the data used to construct it

Intended for use with unit tests, thus saves some interesting information.

Parameters:

plateScalefloat

Plate scale in arcsec/mm; 20.0 is for LSST.

radialDistortionfloat

Radial distortion, in mm/rad^2. The r^3 coefficient of the radial distortion polynomial that converts FIELD_ANGLE in radians to FOCAL_PLANE in mm; 0.925 is the value Dave Monet measured for lsstSim data.

isLsstLikebool.

Make repository products with one raw image per amplifier (True) or with one raw image per detector (False).

Attributes Summary

nDetectors

Return the number of detectors

Methods Summary

makeAmpLists(ampFile[, isLsstLike])	Construct a dict of list of Amplifer, one list per detector.
makeDetectorConfigs(detFile)	Construct a list of DetectorConfig, one per detector
makeTestRepositoryItems([isLsstLike])	Make camera config and amp catalog dictionary, using default detector and amp files.

Attributes Documentation

nDetectors

Return the number of detectors

Methods Documentation

makeAmpLists(ampFile, isLsstLike=False)

Construct a dict of list of Amplifer, one list per detector.

Parameters:

ampFilestr

Path to amplifier data file.

isLsstLikebool

If True then there is one raw image per amplifier; if False then there is one raw image per detector.

makeDetectorConfigs(detFile)

Construct a list of DetectorConfig, one per detector

makeTestRepositoryItems(isLsstLike=False)

Make camera config and amp catalog dictionary, using default detector and amp files.

Parameters:

isLsstLikebool

If True then there is one raw image per amplifier; if False then there is one raw image per detector.
