Alternative Astronomical FITS imaging
  Astronomical radio maps are presented mainly in FITS format. Astronomical
Image Processing Software (AIPS) uses a set of tables attached to the output
map to include all sorts of information concerning the production of the image.
However this information together with information on the flux and noise of the
map is lost as soon as the image of the radio source in fits or other format is
extracted from AIPS. This information would have been valuable to another
astronomer who just uses NED, for example, to download the map. In the current
work, we show a method of data hiding inside the radio map, which can be
preserved under transformations, even for example while the format of the map
is changed from fits to other lossless available image formats.
