Scientific paper

The two morphologically similar nebulae S188 and S274 have been mapped in the radio continuum at 2.7 and 5 GHz. The sources seem to have thermal spectra and the new data effectively rule out that either or both are shell-type supernova remnants. It is demonstrated that a number of distance-independent parameters of the nebulae are closely similar and all present evidence indicates that both are old planetary nebulae. On this hypothesis, the distances of the nebulae are estimated from the radio data. A number of other parameters of the objects are considered in the light of these distances.
