A maximum entropy algorithm is used to combine various data in order to obtain 7.5-arcsec resolution images of the CS J = 2-1 emission from a 3.5-arcmin section of the Orion molecular ridge. This section of the ridge is found to contain four condensations with nearly thermal CS peak brightness temperatures, dimensions from 0.03-0.11 pc, and virial masses from 30-80 solar masses. About 70 percent of the total mass within the 3-arcmin region is shown to be contained in these condensations. It is suggested that the condensations and the included section of the ridge form a gravitationally bound subunit of the Orion cloud. 27 references.
