Before adding WCS to polar plot, we could extract the pixel area with
'--pixelareaarcsec2' option in 'astfits'.

But now after adding the WCS, with following command I have tried to obtain
the pixel area but it does not work and I faced with an erroe which is: 


$ astfits polar.fits -h2 --pixelareaarcsec2

astfits: polar.fits (hdu: 2): dimension 2 doesn't have a unit of degrees
(value to 'CUNIT2'), but 'pix'! In order to use '--pixelareaarcsec2', the
units of the WCS have to be in degrees
