* 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.
Owing to the high latitude of this survey, the longitude spacing of the observations is 0.1429°,
slightly larger than our normal "beamwidth" spacing of 0.125°. For incorporation into the whole-Galaxy cubes
presented elsewhere in this archive, these spectra were interpolated onto a standard beamwidth spaced grid.
