Strip photometry of diffuse objects. I. The structure of comets Kohoutek (1973 XII) and Bradfield (1974 III).
Abstract
A high signal-to-noise ratio and good one-dimensional resolution are obtained by scanning a narrow slit across extended objects. Several observations of two comets give information on total brightness and on the density distribution of the coma. The characteristic scale length, reduced to 1 AU, of the coma of comet Bradfield was 10 to the 4.8 (plus or minus 0.1) power km, in agreement with that of C2 in comet Bennet (1970 II) obtained by Delsemme and Moreau (1973). For comet Kohoutek a slightly larger value was obtained, 10 to the 5.0 (plus or minus 0.1) power km.
