In a strip 20° wide around the galactic equator, extending from l = 340° to l = 220°, line profiles were measured at 620 points. The interval in latitude was 2°·5, the longitude interval was 2°·5 from l = 340° to 110°, and 5° from l = 115° to 215°. At some longitudes the latitude range was extended to ±.
