摘要：

We present observations of 1200 neutral hydrogen spectra measured over a 2-degrees x 6-degrees field, centred at RA 10h07m00s, Dec. 53-degrees, which is currently the subject of a ROSAT deep field survey. The column densities measured range from 0.4 to 1.3 X 10(20) cm-2, and significant changes in velocity structure are seen. The northern part of the field (i.e. > 52-degrees) shows systematically lower column densities than does the southern part.
