Two considered theoretical models are: 1) a shell with constant emissivity and 2) a synchrotron shell with radially aligned magnetic field. The codes were applied to several observed supernova remnants. Good results are obtained in five considered cases, which justify the use of our code for remnants that are bright (so that observational errors are not large) and spherically symmetric enough. |
