[daip] precess images in AIPS

[Saskia Prins]

Dear AIPS support,

I would like to compare 2 VLA maps, overplot contours, make spectral index
maps, etc.  Image nr 1 (from 1992) is in 1950 coordinates, image nr 2
(from 1996) in 2000 coordinates.  I was hoping OHGEO would do the
precession for me, but it does not.  Is there a task in AIPS for
precessing of the WCS header information, (similar to tprecess in IRAF) ?  
I looked through the index, but found nothing obvious.

Best regards,

Saskia Prins
