IMAGR is still useful but there does seem to be a push to add capability
for various calibrations - e.g. direction dependent SN tables, beam
squint (really only VLA), more complex beam pattern info, etc. - which
IMAGR does not now do. There is also a push to include spectral index
imaging in the process. IMAGR's current capability there is quite
limited - I will see if Urvashi's work produces something that looks
like it could be copied or adapted.
In the long run, a package like casa may be necessary but they have not
demonstrated it. The enhancements do seem to be more
instrument-specific too so LOFAR may well have its own needs. Perhaps
Bill Cotton's OBIT is a good compromise with a parseltongue front-end,
aips compatibility, and already direction-dependent SN tables, etc.
