摘要：

Four small-diameter supernova remnants (SNRs) have been mapped with the Fleurs synthesis radio telescope; the maps are the first to reveal structure in these SNRs, all of which lie near zero declination, where most other synthesis telescopes do not provide satisfactory north-south resolution.Three of the sources (G15.9 + 0.2, G27.4 + 0.0 and G41.1 - 0.3) show clear indications of a shell structure; the remaining source, G39.2 - 0.3, may be a rarer variety of SNR showing centrally concentrated emission similar to the Crab Nebula. © 1982 Royal Astronomical Society.
