◆ pixelScaleArcseconds()

def 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
