<DIV> I was using JMFIT in 31DEC08 AIPS to model a simple 2-d
gaussian. The component is compact, well-defined and has good
SNR relative to the background. In the deconvolution section of the
report, the recovered values of the major and minor axes are given in
both pixels and arcseconds, and the position angle (PA) in degrees.
However, the PAs accompanying the pixel-scaled values and the astronomical
angular values are different, and by significant amounts (e.g 20 degrees in a PA
of 131 degrees). Surely, the deconvolved PA is independent of whatever
units I use to report the major and minor axes? Or have I missed something
here?</DIV>
