Maximum Inflation factor for UV_RESTORE (MULTISCALE method). If the number of true (i.e. pixel based) Clean components found by MULTISCALE is larger than CLEAN_INFLATE times the number of compressed (i.e. those with the smoothing factor information) components, expansion of the compressed components will not be possible, and UV_RESTORE or CLEAN /RESTART will not be useable.
The default is 121, large enough to handles all expansion, but it might exceed the available memory. Smaller values are often acceptable. Better solutions might be found in the future, and this parameter suppressed. Apart from memory usage, this number has no consequence on the algorithm.
