4.4 Concluding remarks, early science

AIPS itself, and particularly this appendix, do not begin to cover all of the issues that will arise with EVLA data. The increased sensitivity of the EVLA will mean that imaging will no longer be able to ignore effects that are difficult to correct such as pointing errors, beam squint, variable antenna polarization across the field, leakage of polarized signal into the parallel-hand visibilities, etc., etc. These are research topics which may have solutions in AIPS or other software packages such as OBIT and CASA eventually.
