Loop Gain

The loop gain is usually assigned a value between 0.1 and 0.5. The CLEAN algorithm performs better for extended structures if is set to the lower part of this range. However, the time required for the CLEAN algorithm increases rapidly for small . From Thompson et al. (1986), the number of cycles needed for one point source is
