◆ pixelScaleArcseconds()

lsst.pipe.tasks.functors.ComputePixelScale.pixelScaleArcseconds ( self,
cd11,
cd12,
cd21,
cd22 )
Compute the local pixel to scale conversion in arcseconds.

Parameters
----------
cd11 : `~pandas.Series`
    [1, 1] element of the local Wcs affine transform in radians.
cd11 : `~pandas.Series`
    [1, 1] element of the local Wcs affine transform in radians.
cd12 : `~pandas.Series`
    [1, 2] element of the local Wcs affine transform in radians.
cd21 : `~pandas.Series`
    [2, 1] element of the local Wcs affine transform in radians.
cd22 : `~pandas.Series`
    [2, 2] element of the local Wcs affine transform in radians.

Returns
-------
pixScale : `~pandas.Series`
    Arcseconds per pixel at the location of the local WC.
