Function Documentation

◆ _bearingToUnitVector()

geom.Extent2D lsst.pipe.tasks.peekExposure._bearingToUnitVector	(	afwGeom.SkyWcs	wcs,
		geom.Angle	bearing,
		geom.Point2D	imagePoint,
		geom.SpherePoint \| None	skyPoint = None )

protected

Compute unit vector along given bearing at given point in the sky.

Parameters
----------
wcs : `lsst.afw.geom.SkyWcs`
    World Coordinate System of image.
bearing : `lsst.geom.Angle`
    Bearing (angle North of East) at which to compute unit vector.
imagePoint : `lsst.geom.Point2D`
    Point in the image.
skyPoint : `lsst.geom.SpherePoint`, optional
    Point in the sky.

Returns
-------
unitVector : `lsst.geom.Extent2D`
    Unit vector in the direction of bearing.

◆ _estimateMode()

float lsst.pipe.tasks.peekExposure._estimateMode	(	npt.NDArray[np.float64]	data,
		float	frac = 0.5 )

protected

Estimate the mode of a 1d distribution.

Finds the smallest interval containing the fraction ``frac`` of the data,
then takes the median of the values in that interval.

Parameters
----------
data : array-like
    1d array of data values
frac : float, optional
    Fraction of data to include in the mode interval.  Default is 0.5.

Returns
-------
mode : float
    Estimated mode of the data.

◆ isDispersedExp()

lsst.pipe.tasks.peekExposure.isDispersedExp ( exp )

Check if an exposure is dispersed.

Note this is copied from `atmospec.utils.isDispersedExp` to avoid a
circular import.

Parameters
----------
exp : `lsst.afw.image.Exposure`
    The exposure.

Returns
-------
isDispersed : `bool`
    Whether it is a dispersed image or not.

Definition at line 61 of file peekExposure.py.

◆ plotRose()

None lsst.pipe.tasks.peekExposure.plotRose	(	afwDisplay.Display	display,
		afwGeom.SkyWcs	wcs,
		geom.Point2D	imagePoint,
		geom.Angle \| None	parAng = None,
		float	len = 50 )

Display unit vectors along N/W and optionally alt/az directions.

Parameters
----------
display : `lsst.afw.display.Display`
    Display on which to render rose.
wcs : `lsst.afw.geom.SkyWcs`
    World Coordinate System of image.
imagePoint : `lsst.geom.Point2D`
    Point in the image at which to render rose.
parAng : `lsst.geom.Angle`, optional
    Parallactic angle (position angle of zenith measured East from North)
    (default: None)
len : `float`, optional
    Length of the rose vectors (default: 50)

Definition at line 181 of file peekExposure.py.

◆ roseVectors()

dict lsst.pipe.tasks.peekExposure.roseVectors	(	afwGeom.SkyWcs	wcs,
		geom.Point2D	imagePoint,
		geom.Angle \| None	parAng = None )

Compute unit vectors in the N/W and optionally alt/az directions.

Parameters
----------
wcs : `lsst.afw.geom.SkyWcs`
    World Coordinate System of image.
imagePoint : `lsst.geom.Point2D`
    Point in the image
parAng : `lsst.geom.Angle`, optional
    Parallactic angle (position angle of zenith measured East from North)
    (default: None)

Returns
-------
unitVectors : `dict` of `lsst.geom.Extent2D`
    Unit vectors in the N, W, alt, and az directions.
