def lsst.afw.cameraGeom.cameraFactory.makeCameraFromCatalogs	(		cameraConfig,
			ampInfoCatDict

Construct a Camera instance from a dictionary of detector name: AmpInfoCatalog.

Parameters

[in]	cameraConfig	an instance of CameraConfig
[in]	ampInfoCatDict	a dictionary of detector name: AmpInfoCatalog

Returns

camera (an lsst.afw.cameraGeom.Camera)

def lsst.afw.cameraGeom.cameraFactory.makeCameraFromPath	(		cameraConfig,
			ampInfoPath,

	)

Make a Camera instance from a directory of ampInfo files.

The directory must contain one ampInfo fits file for each detector in cameraConfig.detectorList. The name of each ampInfo file must be shortNameFunc(fullDetectorName) + ".fits".

Parameters

[in]	cameraConfig	an instance of CameraConfig
[in]	ampInfoPath	path to ampInfo data files
[in]	shortNameFunc	a function that converts a long detector name to a short one

Returns
