* 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.

Comments

The sampling of this survey was unique among those in the archive -- two interleaved 0.125° grids. For the cubes presented here, the data were spatially smoothed and placed on a single 0.125° grid. The interpolated cube is recommended as it fills in a small number of missing spectra at random locations as well as the 1/4° sampling on the survey's high-longitude edge.
