plane, single missing pixels are filled by linear interpolation, first in l direction, then b.

Comments

This survey was sampled every half-beamwidth (0.0625°), but for the cube presented here, the data have been spatially smoothed by convolution with a 2d gaussian with fwhm=0.125° and then put on a 0.125° grid. This improves the S/N ratio with only a slight loss of angular resolution.
