Abstract:

The Owens Valley Radio Observatory interferometer was used to carry out a program of aperture synthesis in the interstellar neutral hydrogen absorption line. Maps having resolutions of 0.2 kms and about 1.3 arc minutes were produced using a novel Fourier inversion method. This paper is devoted to discussions of the observing and analyzing procedures and of the results for the Perseus arm feature in the spectrum of Cassiopeia A. Author Modified Abstract
