dc.description.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 10⁴·⁸±⁰·¹ km, in agreement with that of C₂ in comet Bennet (1970 II) obtained by Delsemme and Moreau (1973). For comet Kohoutek we obtained a slightly larger value, 10⁵·⁰±⁰·¹ km. | en |
