Earlier extended surveys with moderate resolution and sensitivity had shown that high-velocity gas can appear as small clouds (∼2°) either isolated, or in elongated complexes with lengths of up to 30°. The profiles were rather broad (halfwidths of 25 km/s). While the brightest HVC's were found in the northern galactic hemisphere, the highest negative velocities were found in the southern latitudes. The only known high-positive velocity objects were a few at low latitudes between 1 = 245° and 330°.
