orientation angles of SDSS images wrt North

I was happy using the position angles of galaxies relative to SDSS image's y axis, but people in the collaboration needed the absolute position angles with respect to the North. I used astroLib's astWCS.getRotationDeg() function, in this script. Didn't test yet, I don't know if that makes sense.
