Abstract: The large scale distribution of 21 cm self absorption in the Taurus Molecular Complex has been determined from observations made by us at Arecibo Observatory in October 1985. Results have been compared with ¹³CO previously observed by Kleiner and Dickman at FCRAO. The principal conclusions drawn from a two-dimensional auto and cross-correlation analysis are: (1) The cold atomic hydrogen in the Taurus Complex has an extremely well defined condensation scale length of 14 pc, as was found for CO. (2) The 21 cm and CO column densities are essentially uncorrelated. Previous thinking would have predicted a high degree of correlation if the HI and CO were well mixed, or a high degree of anticorrelation if the atomic hydrogen was distributed in shells around the molecular gas.
