Detailed Description

Class to project the focal plane onto the sky.

Parameters
----------
camera : `lsst.afw.cameraGeom.Camera`
    Camera from the butler.
defaultOrientation : `int`
    Default camera orientation in degrees.  This angle is the position
    angle of the focal plane +Y with respect to north.
useScienceDetectors : `bool`, optional
    Use only science detectors in projector?

Member Function Documentation

__call__()

lsst.fgcmcal.focalPlaneProjector.FocalPlaneProjector.__call__	(		self,
			orientation,
			nstep = 100,
			use_cache = True )

Make a focal plane projection mapping for use with fgcm.

Parameters
----------
orientation : `float` or `int`
    Camera orientation in degrees.  This angle is the position
    angle of the focal plane +Y with respect to north.
nstep : `int`
    Number of steps in x/y per detector for the mapping.
use_cache : `bool`, optional
    Use integerized cached lookup.

Returns
-------
projectionMapping : `np.ndarray`
    A projection mapping object with x, y, x_size, y_size,
    delta_ra_cent, delta_dec_cent, delta_ra, delta_dec for
    each detector id.

_compute_cached_projection()

lsst.fgcmcal.focalPlaneProjector.FocalPlaneProjector._compute_cached_projection ( self, orientation, nstep = 50 )

protected

Compute the focal plane projection, with caching.

Parameters
----------
orientation : `int`
    Camera orientation in degrees. This angle is the position
    angle of the focal plane +Y with respect to north.
nstep : `int`
    Number of steps in x/y per detector for the mapping.

Returns
-------
projectionMapping : `np.ndarray`
    A projection mapping object with x, y, x_size, y_size,
    delta_ra_cent, delta_dec_cent, delta_ra, delta_dec for
    each detector id.

_compute_projection()

lsst.fgcmcal.focalPlaneProjector.FocalPlaneProjector._compute_projection ( self, orientation, nstep = 50 )

protected

Compute the focal plane projection.

Parameters
----------
orientation : `float` or `int`
    Camera orientation in degrees. This angle is the position
    angle of the focal plane +Y with respect to north.
nstep : `int`
    Number of steps in x/y per detector for the mapping.

Returns
-------
projectionMapping : `np.ndarray`
    A projection mapping object with x, y, x_size, y_size,
    delta_ra_cent, delta_dec_cent, delta_ra, delta_dec for
    each detector id.

_makeWcsDict()

lsst.fgcmcal.focalPlaneProjector.FocalPlaneProjector._makeWcsDict ( self, orientation )

protected

Make a dictionary of WCSs at the reference boresight position.

Parameters
----------
orientation : `int`
    Orientation in degrees.  This angle is the position
    angle of the focal plane +Y with respect to north.

Returns
-------
wcsDict : `dict`
    Dictionary of WCS, with the detector id as the key.
