[alma-config] short spacing

[Leonia Kogan]

The short baselines measurments are important for expanded sources with 
much information at the low spatial frequencies. The sources used at the 
current simulation (SYG, M51..) are the sources of such a type.

If the source does not have much contribution at the low spatial frequencies,
then short baselines are not so important for such sources.

The clusters of compact sourses is an example of the source with small
contribution at the low spatial frequencies.

Is such type of the sources on the line to make a simulation?
