Abstract

The results of spectrophotometric observations in the galactic supernova remnants (SNR) RCW 86, 103 and Kepler are presented. The measurements were made with an angular resolution of about 4 arcsec in a number of different positions in each object. The authors also present the integrated spectra of the three remnants and compare them with the spectra of other galactic SNRs. The differential measurements reveal variations from point to point in the extinction towards the three objects, as well as in their intrinsic relative line-intensities. Some implications of the observed variations are discussed in the context of abundances and shock conditions.
