| Abstract: |
In practical applications, one or more of the simplifying assumptions that were used in Lectures 1 and 2 to derive the relationships between the interferometer visibility measurements and the image of the sky may be violated. Serious violations of these assumptions result in distortions and/or errors in the image. Practical considerations, such as finite computer resources, may also occasionally create difficulties. This lecture addresses several potential problems from a practical point of view. The general nature of the problems is described, as are the conditions under which they become important. Finally, it discusses techniques that can be used to reduce the distortions and/or the errors introduced into images, and to reduce the computing requirements. |
