* In each spectrum, <= 2 missing channels are filled by linear interpolation. In each spatial
plane, single missing pixels are filled by linear interpolation, first in l direction, then b.
The survey was conducted with the 100 kHz filterbank on the southern telescope, providing a velocity resolution of 0.26 km/s over 67 km/s. The velocity
range in the cube is narrow, -10 to 8 km/s, but apparently adequate to cover all the emission from the Coalsack cloud.
